25
Person Perception
refers to the mental processes we use to think about and evaluate other people.
- person perception leads us to make judgements based on limited information that may be inaccurate, first impressions can be influenced by expectations, biases, and incomplete information. aka physical cues
26
attitude

eg. “i feel scared when i see a snake”
behavioural component (actions)-
the way in which attitude is expressed through our actions
eg. “i avoid snakes and scream if i see one”
cognitive component (beliefs)-
beliefs we have about an object, person, group, event or issue.
eg. “i think snakes are gross and dangerous”
28
cognitive dissonance

or
that their behaviour conflicts their cognitions.

SPE aims
To explore how situational factors and assigned roles influence behavior in a simulated prison setting.
45
SPE hypothesis
Participants will conform to their roles as guards or prisoners and exhibit extreme behaviors.
46
SPE participants
24 male college students, selected for psychological stability and physical similarity.
47
SPE results
Guards became abusive, prisoners became submissive and emotionally distressed, leading to the experiment's early termination.
48
SPE Conclusion
The study demonstrated that people would conform to assigned roles and that power dynamics could lead to extreme behaviors
49
SPE ethical issued
Informed consent, psychological harm, lack of intervention, inadequate debriefing.
50
SPE IV and DV
iv- role assigned
dv- behaviours
51
obidience
occurs when we follow the commands of someone with authority, or the rules, or laws of our society.
52
milligrams experiment aims, IV, DV, hypothesis and participants
Aim-To investigate the extent to which people would obey authority figures, even when the actions conflicted with their conscience.
Hypothesis -Milgram hypothesized that people would obey authority figures even when asked to perform harmful actions, due to the strong influence of authority.
Independent Variable (IV)- The authority figure's presence and commands (the experimenter’s instructions).
Dependent Variable (DV)- The level of shock the participant was willing to administer to the learner.
Participants- 40 male participants aged 20–50, from various professions and educational backgrounds.
53
milligrams experiments results and ethical issues
Key Results - 65% of participants administered the maximum 450-volt shock.
- All participants went up to at least 300 volts, at which point the learner screamed and fell silent.
Ethical Issues 1. Deception: Participants were misled about the true purpose of the experiment (they thought the shocks were real).
2. Informed Consent: While participants consented to take part, they were not fully informed about the nature of the study or the potential distress it would cause.
3. Psychological Harm: Many participants showed signs of stress, such as sweating, nervous laughter, and even one participant having a seizure.
4. Right to Withdraw: Although participants were told they could leave at any time, the experimenter’s prompts ("Please continue") made it difficult for participants to feel free to withdraw.
5. Debriefing: The participants were not adequately debriefed immediately after the study, and many were left with feelings of distress, believing they had caused real harm to the learner.
54
conformity
tendency to adjust once thought feelings of behaviours so that they are more consistent with those of other people, or with accepted standards about how person should behave in certain situations
55
asches experiment on conformity
im To investigate the extent to which social pressure from a majority group could influence an individual to conform, even when the group’s answer is obviously wrong.
Hypothesis Asch hypothesized that participants would conform to the majority opinion, even if it was incorrect, due to group pressure.
Independent Variable (IV) The presence and responses of confederates who provided either correct or incorrect answers (the group majority).
Dependent Variable (DV) The participant's response to the comparison lines (whether they conformed to the group's incorrect answer or gave the correct response).
Participants 123 male college students, each taking part in groups of 7–9 people (with the real participant always seated last or second-to-last).
Key Results - 37% of participants conformed to the wrong answers on the critical trials.
- 75% of participants conformed at least once.
- 25% of participants never conformed.
Ethical Issues 1. Deception: Participants were deceived about the true nature of the study, believing it was a "vision test" rather than a study on conformity.
2. Informed Consent: The participants did not know they were taking part in a conformity experiment, which violated the principle of informed consent.
3. Psychological Harm: The study caused some participants stress, as they were put in a situation where they were forced to go against their own perceptions to fit in with the group. Some later reported feeling embarrassed or upset.
4. Right to Withdraw: Although participants could technically withdraw, the pressure to conform made it hard for them to feel comfortable doing so.
56
DeIndividuation
Reduce self awareness, inhibiting feelings of personal responsibility and inner restraint that can occur when in a crowd
57
group size
His results showed that conformity increased with group size
58
unanimity
complete agreement, among the other group members as to what the answer is.
59
informational influence
occurs when conformity results from a need for direction and information on how to respond in a specific situation.
60
normative influence
to conform occurs when our response in a group situation is guided by one or more social norms.
61
culture
) than in other parts of the world such as Africa, Fiji and Asia (e.g. Hong Kong and Japan).
62
social loafing
the tendency of an individual to make less effort when involved in a group activity than when working alone.
63
sensation vs perception
sensation- Detection of raw sensory input (e.g., light, sound) Physical process involving sensory receptors
perception-
Interpretation and organization of sensory input Cognitive process involving the brain
64
attention
the process of focusing on specific stimuli or aspects of the sensory environment whilst ignoring and therefore excluding others.
65
sustained attention
maintenance of attention on a specific stimulus or task for a continuous period of time without being distracted
66
divided attention
ability to distribute our attention so that two or more activities may be performed simultaneously.
67
selective attention
choosing and attending to a specific stimulus whilst at the same time excluding other stimuli
68
top down processing
a perceptual process that starts ‘at the top’ with higher level ‘cognitive processing’ in the brain and then works ‘down’ from the whole to the details
69
figure ground
Gestalt principle of visual perception, that involves organising visual information by perceptually dividing a visual scene into a ‘figure’, which stands out from the ‘ground’, which is its surroundings
70
similarity
Gestalt principle of visual perception that involves a tendency to perceive parts of a visual image that have similar features, such as size, shape, texture or colour, as belonging together in a unit, group or ‘whole’
71
proximity
Gestalt principle of visual perception, that involves a tendency to perceive parts of a visual image which are positioned close together as belonging together in a group; also called nearness
72
73
depth cues
sources of external cues or internal cues that help us perceive how far away objects are and therefore percieve depth
74
convergence
changes in tension in the eyes involving the brain detecting and interpreting depth. the greater tension in the eyes when the object is close and less tension when the object gets further away
75
retinal disparity
slight difference in location of the images on the retina due to the eyes being slightly apart
76
accommodation
the automatic adjustment of the shape on the lens to focus on an object in response to changes in how far away the object is. The lens bulges for close objects and elongates for far objects.
77
linear perspective
the apparent convergence of actual or imagined parallel lines as they recede into the distance
78
interposition
occurs when one object partially blocks or covers another, and he partially blocked object is percieved as further away than the object that obscures it
79
texture gradient
the gradual reduction of the detail that occurs in an object or surface as it recedes into the distance, compared with an object or surface that is close and perceived in fine detail.
80
relative size
refers to the tendency to visually percieve the object that produces the largest image on the retina as being closer, and the object that produces the smallest image on the retina as being further away
81
height in the visual field
refers to the location of objects in our field of vision, whereby objects that are located closer to the horizon are perceived as being more distant than objects located further from the horizon
82
perceptual set
a temporary readiness to perceive something in accordance with expectations of what it is
83
what factors affect perceptual set
past experience, motivation, context
84
visual illusion
misperception of external visual stimuli that occurs as a result of a distortion or mistake when interpreting the stimuli
85
why do illusions occur?
heuristics, top down processing, depth perception, contrasting and ambiguous sensory imput
