Questions and Answers

Critically evaluate the claim that the replication crisis in psychology stems primarily from a misunderstanding of the philosophical underpinnings of empiricism.

The replication issues may not be from empiricism itself, but rather with methodological issues within psychology and biases of researchers. Philosophy and method were never properly combined to have a proper interpretation of statistical data.

Contrast the epistemological assumptions of structuralism with those underpinning cognitive psychology, highlighting the implications for methodology and the types of questions each approach can address.

Structuralism relies on breaking down mental processes into elements using introspection. Cognitive psychology constructs testable models on how the brain works using scientific experimentation. This means structuralism is limited by subjectivity whereas cognitive psychology has clear objective standards.

Develop a novel experimental paradigm that integrates principles from both behaviorism and cognitive psychology to investigate the role of implicit cognitive processes in shaping observable behavior. Focus on the ethical implications of your experiments.

Subliminal priming experiments could be created, where the subject is exposed to subconscious stimuli. Then, the observable behaviour is recorded with its effect. It must be ensured they have given informed concent, and the priming cannot be harmful or emotionally damaging.

Deconstruct the socio-cultural approach to psychology through the lens of intersectionality, illustrating how multiple dimensions of identity (e.g., race, gender, socioeconomic status) interact to shape individual experiences and behaviors.

<p>Multiple dimensions of identity interweave to create a complex experience. For example, a low-income disabled individual may feel neglected by healthcare in a way that a wealthy individual may not, or even a low-income non-disabled individual may not.</p> Signup and view all the answers

Formulate a research proposal that investigates the neural mechanisms underlying neuroplasticity in the context of complex skill acquisition, while specifically addressing the challenge of isolating task-specific neural changes from general adaptive processes.

<p>This may involve longitudinal neuroimaging such as FMRI and computational modeling of brain connectivity to isolate changes specific to skill acquisition from general adaptive brain processes.</p> Signup and view all the answers

Critically analyze the methodological limitations of Harlow's research on attachment in rhesus monkeys, particularly regarding the generalizability of his findings to human populations and the ethical considerations of his experimental design. Could these limitations be solved by technology?

<p>There's no guarantee findings will transfer effectively. The ethics would need to be weighed against the goal of the experimetn. Virtual Reality can simulate social and physical environments, allowing for controlled experiments without direct physical harm.</p> Signup and view all the answers

In what ways might Shaver and Hazan's findings on adult attachment styles be confounded by retrospective bias and self-report measures, and how could future research designs address these limitations?

<p>Retrospective bias is when participants inaccurately recall experiences, while self-report measures are vulnerable to biases in answers due to social expectations. Longitudinal studies and implicit measures could mitigate these limitations.</p> Signup and view all the answers

How does the concept of 'strange situation' paradigm need to be adapted, in terms of design and interpretation, to be culturally sensitive and representative of diverse parenting styles across various global contexts, including accounting for cross-cultural differences?

<p>It would need to consider cultural norms regarding child-rearing practices. Use of local reseachers would further help and qualitative data to contextualise findings and ensure appropriateness in diverse settings.</p> Signup and view all the answers

How does the modern reconceptualization of secure base theory consider the roles of digital technologies and virtual interactions in contemporary attachment relationships, especially in the context of geographically separated families?

<p>Digital tech may offer a form of secure base, especially when physical presence is impossible. Texting, videoconferencing, and social media need to be studied to understand how they influence attachment.</p> Signup and view all the answers

Develop a research hypothesis that integrates evolutionary psychology principles with attachment theory to explain the potential adaptive functions of avoidant attachment styles in specific environmental contexts.

<p>Avoidant attachment is useful in dangerous and unpredictable enviornments since it avoids parental attention, as well as resources may be limited and the child would be required to be more independant to survive. This may involve lower energy consumption.</p> Signup and view all the answers

Critically assess the claim that the rise of cognitive psychology represents a paradigm shift in the Kuhnian sense, considering its intellectual origins, methodological innovations, and impact on other subfields of psychology.

<p>The shift may be considered not only as methodological, but has also shifted focus on the unobservable mental processes. Whether a paradigm shift also includes major reassessments about theories and perspectives is a matter of debate.</p> Signup and view all the answers

<p>Gestalt principles can be applied, such as proximity (grouping related elements), similarity (using common elements), closure (creating complete objects from fragments), and figure-ground (distinguishing important from background info) to improve user interface design.</p> Signup and view all the answers

Detail the current limitations in psychophysics, emphasizing on those that relate to ecological validity and the experimenter effect on measuring perception and sensation.

<p>Psychophysics may not mirror the complexity of real-world experiences due to controlled experiments not exactly emulating the real world. Therefore, the lab conditions do not fully simulate the real world.</p> Signup and view all the answers

What are the primary problems in attempting to apply the principles of physics to psychological phenomena, particularly with respect to issues of reductionism and emergent properties?

<p>Physics often involves simplifying systems, while cognition is complex with emergent properties not easily reducible to lower biological level processes. This makes it difficult to translate physics theories to psychology.</p> Signup and view all the answers

Given the reproducibility crisis in psychology, assess the methodological changes most needed to improve the reliability and validity of experimental research; focus on the balance between standardization and ecological validity.

<p>Pre-registration, open data sharing, usage replication studies, and robust statistical methods are crucial in enhancing both reliability and validity. Balancing standardization with ecological validity requires innovative experimetnal design.</p> Signup and view all the answers

Compare and contrast the approaches of Wilhelm Wundt and William James in terms of their methodologies and their contributions to the establishment of psychology as a distinct scientific discipline.

<p>Wundt was more structured, where his goal was to break experience into component parts, while James focused on mental processes to help survival. Wundt used more controlled experiments, while James's work considered broader context of behaviour.</p> Signup and view all the answers

Explain how advancements in genetic research and neuroimaging techniques have refined and challenged the core tenets of the biological approach to psychology, particularly concerning the nature versus nurture debate.

In what specific ways does the application of evolutionary principles to human behavior risk perpetuating problematic assumptions about group differences and social hierarchies?

<p>Using evolution to explain behaviour leads to justifications of social inequalities as natural. This can reinforce discrimination based on race, gender, and socioeconomics by implying genetic differences explain group disparities. Such arguments assume genetic determinism.</p> Signup and view all the answers

Study Notes

  • Psychology is the scientific study of behaviors (external effects) and cognition and emotions (internal mental processes), aiming to describe, explain, predict, and control using the scientific method.
  • Psychology is an integrative science influenced by philosophy, biology, and physics.
  • Science seeks knowledge and understanding through systematic methodology and empirical evidence, minimizing biases and reporting methods clearly.
  • Empiricism posits that knowledge comes from experience.
  • Limitations of science include subjectivity, moral and cultural considerations, accuracy, reliability, inconclusive data, untestable concepts, and the inability to reproduce experiments perfectly.
  • Operationalization involves creating and testing functional data surrogates for abstract concepts.
  • Ethical considerations limit the reproduction of harmful elements in experiments.
  • Hypothesized correlations can substitute for causation when manipulation isn't possible.
  • Scientific research should be reliable, accurate, and conducted to scientific standards.
  • Cross-sectional studies occur once, while longitudinal studies track subjects over time.

Approaches

  • Structuralism (late 1800s): Focused on the conscious mind and its component parts through introspection, but was limited in its explanatory power.
  • Functionalism: Viewed mental processes as functional for survival and adaptation, addressing the causes of behavior and thoughts.
  • Gestalt (early 1900s to 1950s): Emphasized the importance of the whole experience rather than individual parts.
  • Psychoanalysis (early 1900s to present): Focuses on the unconscious mind and utilizes therapy.
  • Behaviorism (early 1900s to 1960s): Advocated for objective study of observable behaviors alone.
  • Cognitive Psychology (1950s to present): Uses testable models and scientific methods to understand brain function.
  • Humanistic Approach (1950s to present): Examines the individual’s conscious experience and life aims.
  • Biological Approach (1950s to present): Explores evolutionary, physiological, and genetic explanations.
  • Socio-cultural Approach (1960s to present): Considers social and cultural influences on mental processes.

Pseudoscience

  • 'Common sense psychology' relies on life experiences to form opinions but often leads to inaccurate conclusions.
  • Casual relationships don't necessarily prove or predict outcomes.
  • Experiments isolate effects by manipulating one variable while keeping controls consistent.
  • Placebos must be considered in experiments.

Harry Harlow’s Secure Base Theory

  • Infants need a secure base to explore their environment and grow cognitively.
  • Infants use caregivers as a secure base during exploration. Contact comfort is vital
  • Infants preferred a cloth mother regardless of nursing condition and adoptive parents were as effective as biological ones
  • Ethical considerations and applicability to humans need to be considered regarding his studies.
  • Proper attachment is essential for cognitive growth, and its absence can disrupt development.
  • Secure base theory changed ‘basic care’ in orphanages, emphasizing the importance of human contact.
  • Neuroplasticity is the brain’s ability to adapt its structure and function throughout life.
  • Monkey brain chemistry may differ depending on whether they were raised with cloth or wire mothers.
  • Imprinting differs from attachment as a rapid, instinctive learning period during a critical period of life, while attachment is a complex bond with various emotional facets.
  • Imprinting is important to forming a child's sense of identity and learning behaviours of the species to follow.
  • Imprinting can facilitate mother identification through auditory and visual means, creating a sense of belonging.
  • A bond that is demonstrated by feeling of security in the child in the presence of the caregiver -> feel secure and comfortable with them, anxious and insecure without them, is critical to the development of the child

Ainsworth - Strange Situation Paradigm

  • Type A (Avoidant Attachment): 20% of infants, no distress when the mother leaves, indifferent, and no anxiety with strangers.
  • Type B (Secure Attachment): 70% of infants, separation anxiety, avoids stranger when alone but is friendly with the mother, and shows a clear positive reaction upon reunion.
  • Type C (Ambivalent/Resistant Attachment): High separation anxiety, resists contact, and may push the mother away upon reunion; the stranger is always present.

Cultural Variation

  • Intracultural variation can be significant and impact on the samples, where I:C 1.5:1.
  • Socio-economic status can influence attachment styles; middle-class families show higher rates of secure attachment.
  • Secure attachment (B) is the most dominant style across all cultures.
  • Avoidant attachment (A) prevalent in Western Europe possibly due to pushing infants to more independence and higher of ambivalent in Israel and Japan to be rare contact with strangers in childhood.
  • Social behaviors have a significant impact on infant attachment behavior.

Attachment in Adulthood

  • Attachment behaviors become more complex and diverse as individuals develop self-regulation of relationship models.
  • Adult attachment patterns often mirror those from childhood caregiver relationships.
  • Childhood attachment may influence behavioral patterns in adult romantic relationships.
