Study Notes

Distribution of one Variable

Researchers studied cancer patient reading levels, which is a variable that varies based on individual factors like education, age, and health status.

Statistical Significance

Researchers must look for other variables in the infant study that they may have missed.
To determine if results are significant, researchers use p-values.
A p-value below .05 means the observed mean scores were not coincidental.

Cause and Effect

Statistical tendencies can be observed in data
Random assignments can help to eliminate bias and establish cause and effect.

Scientific Reasoning and Theories

Hypotheses are testable predictions about the way the world works.
Scientists use inductive reasoning to draw conclusions based on observations.

Features of Good Scientific Theory

Accuracy relates to how closely a theory matches real-world observations.
Scope is the range of phenomena a theory explains.
Fruitfulness, refers to a theory’s ability to generate new research.
Simplicity means a theory is easily understood.
Consistency means that a theory fits with other well-established theories.
Falsifiability refers to a theory’s ability to be proven wrong.

Standing Desks and Productivity

Three potential outcomes of a study examining standing desks and productivity:
- Results support the hypothesis that standing desks increase productivity.
- Results contradict the hypothesis, indicating that sitting is more productive, or that there is no difference between the groups

Levels of Analysis

This model helps researchers understand the intricate connections between different aspects of human behavior, ranging from cultural influences to biological processes.
- Social/ Culture
- Behavioral
- Cognitive
- Biological

Research in the Real World

Internal validity is the degree to which a study definitively establishes a relationship between two variables.
External validity is the degree to which a study's findings can be generalized to other settings and samples.
Ecological validity is the degree to which the study's findings apply to everyday life.

Studying Daily Experiences

Day Reconstruction Method (DRM) - participants reconstruct their day systematically.
Electronically Activated Recorder (EAR)- records audio snippets throughout the day.

Replication and Statistical Investigation

Direct Replication: re-running a study with exact same methods.
Conceptual Replication: explores the same phenomena using different methods.
Key components of a statistical investigation:
- Planning the study: Determining research questions and how to collect data.

Chromosomal Sex

Chromosomal sex is determined by the sex chromosomes (XX or XY) received at fertilization.

Hormones and Behavior

Hormones influence various behaviors, including:
- Food and liquid intake
- Social interactions
- Stress responses
- Learning and memory
- Psychopathologies like depression and anxiety

Interacting with Cells

Hormones work through receptors on target cells.
Hormones can regulate gene expression within target cells.

Functions of Hormones

Regulate sensory input systems (afferent)
Integrate cognition (central nervous system)
Control motor output systems (efferent)

Sex Differentiation

The process of becoming male or female.
Organizational effects occur early in development and establish a permanent anatomical structure.
Activational effects occur later and trigger behavioral responses.

Dysfunction

Turner syndrome is a condition where females have only one X chromosome.
5-alpha-reductase deficiency happens when males lack an enzyme needed to convert testosterone into dihydrotestosterone (DHT).
Androgen insensitivity syndrome (AIS) is a condition where individuals with XY chromosomes are insensitive to androgens.

Parental Behavior

Refers to behaviors that contribute to the survival of offspring.

Human Sexual Anatomy and Physiology

Includes the biological structure and function of the reproductive system.

Sexual Dysfunction in Males

Delayed ejaculation
Erectile Disorder (ED)
Male Hypoactive Sexual Desire Disorder
Premature Ejaculation (PE)

Sexual Dysfunction in Females

Female Orgasmic Disorder
Female Sexual Interest/ Arousal Disorder (FSIAD)
Genito-pelvic Pain/ Penetration Disorder

What is Consciousness?

Consciousness is awareness of our experiences, thoughts, feelings, and surroundings.
The "content of language" relates to the subject matter of our thoughts and conversations.

Topics of Conversation: Ingroups and Outgroups

60-70% of everyday conversation is gossip.
Gossip helps humans share representations about and regulate their social world.

Linguistic Intergroup Bias

Refers to the tendency to talk about positive attributes of one's group (ingroup) and negative attributes of other groups (outgroups) using adjectives instead of verbs.

Dunbar (1996) suggested that social effects gave early humans an evolutionary advantage.
This led to larger brains in humans, allowing for more complex thinking.

Key Insights (Chapter 3 Notes)

Consciousness is a topic of ongoing research in psychology and neuroscience.
Distinguishing between conscious and non-conscious processes is important for understanding how our minds work.
Consciousness is influenced by biological, social, and environmental factors.

Key Insights (Chapter 3 Notes Continued)

Selective attention allows us to focus on specific stimuli while filtering out distractions.
Cognitive capacity is limited.
Attention models attempt to explain how we process information.
Inattentional blindness explains how we can miss information when our attention is focused elsewhere.

Nature of Mental Concepts and Categories

Humans categorize objects based on shared properties and prototypes, rather than strict definitions.
The "basic-level category" provides an optimal level of specificity.
Various theories explain concept representation, including prototype and exemplar theories.

Intelligence

Intelligence is multifaceted and influenced by both genetics and the environment.

Key Insights on Intelligence

Notable figures in the study of intelligence include Binet and Spearman.
Different types of intelligence exist, such as emotional intelligence and Gardner’s multiple intelligences.
Intelligence is frequently measured through standardized tests.
The Flynn Effect shows that average IQ scores have increased over time, suggesting environmental influences on intelligence.
Mindset plays a critical role in intellectual performance.

Language and Sociality

Language is a fundamental tool for communication, enabling humans to build and maintain social structures.
Language is learned and utilized through shared knowledge and "common ground" between individuals.
The emergence of Nicaraguan Sign Language demonstrates the innate human capacity for language development.
