Alternative hypothesis
Terminology Internal validity Validity Applicability Matched pairs Alternative hypothesis Replicability Reliability Repeatability Ethicability Individual External validity Concurrent validity Determination Situationalise Longitudinal
3
Observation No cause and effect Can be reductionist
Allows participants to react naturally to stimulus Offers situational explanations of behaviour Can cover a variety of natural situations Allows for easy comparison of behaviours Highly subjective Can present ethical issues Does not show why You can naturally observe the DV Not easily replicable Triangulation Low demand characteristics High ecological validity Does not require consent
4
Experiments Cannot control all confounding variables, affecting validity Concurrent validity Quantitative data Cause and effect Low ecological validity Demand characteristics Controls extraneous variables Always highly ethical Can ignore situational factors Can be easily replicated Objective Allows correlation to be identified Not a valid measure Difficult to apply appropriately Ignores social factors
5
Self-Report Likert scales ‘draw’ responses to the extremes
High in ecological validity Allows thoughts and feelings to be assessed Researcher bias Used to research specific topics Difficult to set an IV and DV Rich, in-depth data Can be subjective Difficult to clarify validity Samples not usually generalisable Social desirability bias Qualitative data Quantitative data Low reliability Likert-scales allow for a quick easy response
6
Correlation Shows a connection between two variables
Can be affected by anomalies Does not use qualitative data Can suggest the strength of a relationship Does not control for any extraneous variables Does not show cause and effect Can be reductionist Reliability is affected by the variables used Lacks any direct applications Is best for physiological studies Has high reliability Has high internal validity Provides the basis for further research Is not ethnocentric Allows study of variables that are awkward to manipulate
7
Cognitive Does not explain how An IV and a DV can be set
Explores thought patterns Easily replicable Offers quantitative data Can sometimes gather qualitative data May not be truly valid Low ecological validity Can be reductionist Can take less time to carry out Could be seen to ignore social aspects Could be seen to be deterministic Has subjective aspects of the variables Derived from behaviourism Validity can be enhanced through replication
8
Developmental Tracks behavioural changes through time
Longitudinal studies Human development is driven by certain forces Behaviour in adulthood is affected by experiences Some behaviours are innate, others are learnt Only looks at a few specific behaviours Focuses overly on childhood Can lead to over generalisation Is interest in behaviours we pick up later in life Use of case studies is not fully generalisable Ignores the individual Allows for set stages of development Focuses on the thought processes behind behaviour Is observation based Snapshot studies result in participant variability
9
Physiological/Biological
Animal testing is ok Behaviours can change throughout our lives Behaviour can affect our neurology Animal testing can be generalised to humans Some behaviours are natural Gender is a physiological factor Cognition and physiology interact Looks intently at a specific factor Can be reductionist Includes DNA and evolution Hormones can affect behaviour Behaviour can affect your environment We learn some of our behaviours Quantitative data is collected We can develop models of behaviour
10
Sociocultural Humans have a desire to belong
People’s views don’t change too much Festinger – Cognitive Dissonance Katz – Black people perform worse on IQ tests out of fear Rabbie and Klee – Minimal Group Paradigm Behaviour is influenced by culture Observations provide ecologically valid data Milgram explored conformity Attributions can be situational or dispositional Zimbardo – the BBC prison study Lee didn’t do fundamental... ROSS Katz not fear – only when told being compared to white people, 60s We can develop stereotypes from our ‘gate-keepers’ Lee – Fundamental Attribution Error Foot-in-the-door, low-balling, reciprocity, begging Bandura – Social Learning Theory Asch – people conform to majorities 1/3 of the time
11
Individual Differences
Is unethical Lacks generalisability Is reductionist Generalise differences, not similarities Self-fulfilling prophecies Ignores the situation Abnormal behaviours Highlights (instead of celebrates) differences Relies on self-report Quasi samples Griffiths, Gambling Baron-Cohen, Autism Study of mental illness Focuses on the individual Demand characteristics
12
Generalisability Who is in a study Whether a study is realistic
Can be improved using a larger sample Can be specific Linked to the application Reduced when using a quasi sample Dependent on sampling method Random sample Dependent on the realism of task All studies are generalisable Who a study applies to Linked to characteristics of sample Dependent on the validity of the measure Some studies are not generalisable Self-selected sample
13
Reliability Affected by the measure of the DV
Are the results consistent? Is the DV measuring what you wanted to? Can be increased with a larger sample Objectivity Low in correlation Subjectivity Linked to a clear procedure Affected by extraneous variables Needs clear controls Qualitative data Affected by ethnocentricity Improved using qualitative and quantitative data Requires a clear IV Can the study be replicated?
14
Application Not the results, the conclusions
Each approach has its own applications Ethics directly affects application Linked to generalisability Improved with ecologically valid situations Affected by reliability Only as good as the generalisability Usefulness How the results can be used Reduced with poor validity Must be linked to the real world Linked to alternate hypothesis Reliable studies have better applications Better with experiments Cause and effect gives direct application
15
Validity Affected by reductionism Matching the aim Affected by sample
Internal validity Truthfulness of the measure Dependent on reliability Improved by lab experiments Poor when using qualitative data Dependent on situation Measuring what is intended External validity Has cause and effect Can be ecological Requires accurate DV measure Reduced by artificial tasks
16
Ethical considerations
Informed consent Dessent Protection from harm Mental health considerations Brief Respect for people’s rights Beneficence and nonmaleficence Fidelity and responsibility Disseminate information Confidentiality Assent Mundane realism Debrief Must benefit human kind Integrity
17
Reductionism Can be simplistic Direct explanations for behaviour
Ignores other explanations Gives great insight To reduce a behaviour to a single factor Can be deterministic Only focuses on one possible cause Involves small factors interacting Lots of data on one topic Social psychology is rarely reductionist Can offer interactionist explanations Is usually objective Offers cause and effect Is a negative aspect of experiments The biological approach is commonly reductionist
18
Determinism Seen in cognitive approach Allows for prediction
Reduces ecological validity Seen in biological approach Can be through prior interaction Does not allow for free will Explains what we should do in a situation Situational explanation Explains individuals behaviours Can be through environment Can be reductionist Explains why we act in certain ways Defines behaviour through effort Created through cause and effect Supports the behaviourist perspective
19
Situational Behaviours caused by the environment
Those around you affecting your decisions Defines behaviours in certain places Piliavin, Subway Samaritan Personals choices about where to go Reducing free will Over-rides inner cognition Shows cause and effect Ignores individual differences Overlooks other factors Explains actions in different environments Conformity and compliance Can be used to predict behaviour As opposed to individual Has ecological validity
20
Ecological Validity Task Situation Mundane reality Observations
Application Control Extraneous variables Experiments Easier to manipulate variables when low Dement and Kleitman, Sleep and Dreaming Internal validity Reliability Either present or not present Only in observations Linked to experimental design

32
Piliavin Cognitive Developmental Physiological Social Individual
More men helped the victim No conclusion was drawn from model’s assistance It was a field experiment Two female confederates ensured gender balance There was some tendency towards same-race help Participants could not leave the area Fewer drunk trials were recorded Results showed diffusion of responsibility Same race help was not a significant finding The Arousal-Cost Reward model was developed from this The victim was either blind or drunk The cane victim received more spontaneous help Ethical aspects reduce ecological validity People may react differently to a female victim Those who didn’t help felt embarassed Cognitive Developmental Physiological Social Individual
