Design an experiment to test whether ostracism during Internet social interactions affects mood and self-esteem, and compare different lineup formats (standard simultaneous, fast elimination, slow elimination) in terms of their impact on eyewitness identification accuracy, including correct identifications, false alarms, misses, and correct rejections. Specify hypotheses, experimental design, variables, procedures, control of extraneous variables, and whether the design is within-subjects or between-groups.

Paper For Above instruction

The investigation into the psychological effects of social treatment online and the efficiency of different eyewitness lineup formats involves two distinct yet interconnected experimental scenarios, each requiring rigorous scientific design to yield valid and reliable results. This paper outlines the hypotheses, experimental design, variables, procedures, and considerations necessary for such investigations, enabling researchers to explore these critical areas within social and cognitive psychology.

Hypotheses

The hypotheses for these experiments are formulated based on the theoretical predictions of social exclusion and cognitive recognition processes. The alternative hypothesis (H₁) for the Internet ostracism study posits that individuals who experience ostracism during online social interactions will exhibit significantly poorer mood and lower self-esteem compared to individuals who are accepted. Conversely, the null hypothesis (H₀) asserts that there will be no significant difference in mood and self-esteem between ostracized and accepted participants. In the eyewitness lineup scenario, the alternative hypothesis suggests that the type of lineup format will significantly influence identification accuracy, with certain formats leading to higher correct identifications and fewer errors. The null hypothesis claims no significant difference in accuracy across lineup formats.

Experimental Design

The study investigating the effects of ostracism on mood and self-esteem employs a single-factor experimental design with two levels of the independent variable: acceptance versus ostracism. Participants are randomly assigned to either the ostracism condition, where they are intentionally excluded during an online interaction, or the acceptance condition, where they are included. This design qualifies as a between-subjects experiment because different participants are exposed to each condition, preventing carryover effects. The eyewitness lineup study utilizes a factorial design with two independent variables: lineup format (standard simultaneous, fast elimination, slow elimination) with three levels, and participant age group (children vs. adults) with two levels. This allows examination of main effects and interactions between lineup type and age group.

Variables and Operational Definitions

In the ostracism experiment, the independent variable is social treatment during the online interaction, manipulated by data-driven scenarios where participants are either included or ostracized. The dependent variables are mood and self-esteem, operationally defined using standardized scales such as the Positive and Negative Affect Schedule (PANAS) and the Rosenberg Self-Esteem Scale, respectively. Mood scores are quantified based on participants’ self-reported affect ratings, while self-esteem is measured through scale responses. In the lineup experiment, the independent variable is lineup format, manipulated by presenting participants either with a simultaneous, fast elimination, or slow elimination lineup. The dependent variables include rates of correct identifications, false alarms, misses, and correct rejections, operationally defined by the participant’s responses classified according to the actual presence or absence of the suspect.

Procedures

Participants for the ostracism study will be recruited from online platforms or university pools, ensuring diversity and sufficient sample size for statistical power. The experiment will be conducted via a secure online survey platform, where participants first complete baseline mood and self-esteem assessments. Subsequently, they engage in a simulated social interaction, designed to either ostracize or accept them, with the manipulation monitored through predefined behavioral cues and participant feedback. Post-interaction, participants re-complete the mood and self-esteem scales to assess changes. To control extraneous variables, factors such as time of day, participant mood prior to testing, and prior online social experiences will be balanced or recorded for covariate analysis.

For the lineup experiments, participants (children and adults) will view video or live presentations of the lineup procedures, simulated either in a laboratory setting or through virtual reality environments designed for controlled viewing. Each participant views multiple lineups in randomized order to mitigate order effects. To control for confounding variables, consistency in the presentation, lighting, and instructions will be ensured. One within-subjects approach can be used, where the same participant experiences all lineup formats with adequate counterbalancing and rest periods to prevent fatigue, habituation, or carryover effects. Matching of participants based on factors such as age, gender, and prior exposure to similar tasks will minimize confounding effects.

Controls and Addressing Confounding Variables

Various strategies will be employed to control extraneous variables. In the ostracism experiment, random assignment ensures equal distribution of potential confounders across conditions. Standardized instructions and interaction scenarios minimize experimenter bias. In the lineup experiments, blinding the experimenters to the lineup condition and randomized presentation order helps eliminate bias. Matching participants on key demographic variables, such as age and prior experience, supports internal validity. To address potential fatigue or habituation in within-subject designs, rest periods and counterbalancing of lineup order will be implemented. These measures promote the reliability of the findings.

Within-Subjects or Between-Groups Design

The ostracism study employs a between-groups design, as each participant is exposed to only one social treatment condition to prevent carryover effects. The eyewitness lineup study can utilize either a within-subjects design—where each participant participates in all lineup types—and counterbalances order effects, or a matched-groups design, where different groups are assigned to each lineup format, matched on relevant demographic factors. Using a within-subjects design for the lineup task is advantageous because it increases statistical power and controls for individual differences, but it necessitates careful planning to prevent fatigue and order effects.

Conclusion

The outlined experimental frameworks provide rigorous methods to investigate the psychological impact of social ostracism online and the effectiveness of various eyewitness lineup formats. By carefully defining hypotheses, selecting appropriate designs, operationalizing variables, and controlling extraneous factors, researchers can generate valid and reliable data. These insights have practical implications for understanding social behaviors in digital environments and improving forensic procedures, ultimately enhancing psychological theory and application in social and cognitive domains.
