paychology weaknesses and strengths

Dement & Kleitman (1957)

Study focusing on REM sleep and its association with dreaming.

Strengths of Dement & Kleitman (1957)

Controlled lab setting ensured high internal validity; objective measures like EEG recordings were used.

Weaknesses of Dement & Kleitman (1957)

Small, mostly male sample limits generalizability; unnatural sleep environment may affect behavior.

Hölzel et al. (2011)

Study examining mindfulness and its effects on brain structure using MRI scans.

Strengths of Hölzel et al. (2011)

Used MRI scans for objective brain measurement; practical application for mental health through mindfulness.

Weaknesses of Hölzel et al. (2011)

Small, self-selected sample introduces bias; short duration limits long-term conclusions.

Andrade (2010)

Study that investigates whether doodling helps attention.

Strengths of Andrade (2010)

Simple and easily replicable procedure; clear cause-effect relationship due to experimental control.

Weaknesses of Andrade (2010)

Mostly female sample reduces generalizability; artificial task may lack ecological validity.

Baron-Cohen et al. (2001)

Study focusing on Theory of Mind in individuals with autism.

Strengths of Baron-Cohen et al. (2001)

Matched groups reduced confounding variables; standardized and validated measures were utilized.

Weaknesses of Baron-Cohen et al. (2001)

Gender imbalance in autism group; may not reflect real-world social understanding.

Pozzulo et al. (2012)

Study on eyewitness accuracy comparing children and adults.

Strengths of Pozzulo et al. (2012)

Age comparisons offer developmental insight; relevant to real-life legal contexts regarding eyewitness testimony.

Weaknesses of Pozzulo et al. (2012)

Children may interpret tasks differently; opportunity sample may not be representative.

Bandura et al. (1961)

Study on observational learning of aggression in children.

Strengths of Bandura et al. (1961)

Large sample and matched participant design; controlled environment enhances internal validity.

Weaknesses of Bandura et al. (1961)

Exposes children to aggressive behavior (ethical issue); sample limited to American children.

Fagen et al. (2014)

Study utilizing naturalistic observation to explore social learning in elephants.

Strengths of Fagen et al. (2014)

Naturalistic observation adds ecological validity; captured real social learning in elephants.

Weaknesses of Fagen et al. (2014)

Difficult to control variables in the wild; small sample limits generalization.

Hassett et al. (2008)

Study on toy preferences in monkeys aimed at understanding biological impacts.

Strengths of Hassett et al. (2008)

Controlled conditions ensured consistency; ethical advantages over human trials.

Weaknesses of Hassett et al. (2008)

Questionable generalizability to humans; anthropomorphism may bias interpretation.

Saavedra & Silverman (2002)

Case study treating a boy with a button phobia.

Strengths of Saavedra & Silverman (2002)

Rich, detailed case study data; therapy success demonstrates real-world effectiveness.

Weaknesses of Saavedra & Silverman (2002)

Based on a single case, cannot generalize; researcher bias possible in interpretation.

Milgram (1963)

Study investigating obedience to authority figures.

Strengths of Milgram (1963)

Highly controlled procedure; revealed key insights about the nature of obedience.

Weaknesses of Milgram (1963)

Ethical concerns regarding deception and stress; all-male, American sample.

Piliavin et al. (1969)

Study on bystander behavior in a subway setting.

Strengths of Piliavin et al. (1969)

High ecological validity due to real subway setting; large, diverse sample.

Weaknesses of Piliavin et al. (1969)

Lack of informed consent; many variables were not controlled.

Perry et al. (2015)

Study examining norms of personal space across various contexts.

Strengths of Perry et al. (2015)

Real-world application of findings regarding personal space norms; varied methods and populations used.

Weaknesses of Perry et al. (2015)

Cultural bias may skew findings; sampling may not be evenly distributed.
