Choice among two and three alternatives

Although choice between two alternatives has been widely researched, fewer studies have examined choice across multiple (more than two) alternatives. Past models of choice behavior predict that the number of alternatives should not affect relative response allocation, but more recent research has found violations of this principle. Five pigeons were presented with three concurrently scheduled alternatives. Relative reinforcement rates across these alternatives were assigned 9:3:1. In some conditions three keys were available; in others, only two keys were available. The number of available alternatives did not affect relative response rates for pairs of alternatives; there were no significant differences in behavior between the two and three key conditions. For two birds in the three‐alternative conditions and three birds in the two‐alternative conditions, preference was more extreme for the pair of alternatives with the lower overall pairwise reinforcer rate (3:1) than the pair with higher overall reinforcer rate (9:3). However, when responding during the changeover was removed three birds showed the opposite pattern in the three‐alternative conditions; preference was more extreme for the pair of alternatives with the higher overall reinforcer rate. These findings differ from past research and do not support established theories of choice behavior.     

Sleep quality in healthy and mood-disordered persons predicts daily life emotional reactivity

Disordered sleep has been linked to impaired emotional functioning in healthy and depressed individuals. Little is known, however, about how chronic sleep problems influence emotional reactivity in everyday life. Participants with major or minor unipolar depressive disorder (n?=?60) and healthy controls (n?=?35) reported on sleep and emotional responses to daily life events using a computerised Experience Sampling Method. We examined whether impaired sleep quality influenced emotional reactivity to daily events, and if this relationship was altered by unipolar mood disorders. Among healthy individuals, sleep difficulties were associated with enhanced negative affect (NA) to unpleasant events and a dulled response to neutral events. However, among mood-disordered persons, sleep difficulties were associated with higher NA across all types of everyday life events. Impaired sleep quality differentially affects daily life emotional reactions as a function of depression.     

Getting to Know Me: Social Role Experiences and Age Differences in Self‐Concept Clarity During Adulthood

ABSTRACT The current research had 2 aims: (1) to determine the cross‐sectional age differences in self‐concept clarity during adulthood and (2) to examine the importance of social role experiences for age differences in self‐concept clarity. These aims were addressed in 2 large samples of adults ranging in age from 18 to 94 years. In both studies, self‐concept clarity had a curvilinear relation to age such that self‐concept clarity was positively related to age from young adulthood through middle age and negatively related to age in older adulthood. This relationship was moderated by annual income and community investment. In addition, annual income and health‐related social role limitations mediated age differences in self‐concept clarity. Findings are discussed in terms of modern theories of identity development.     

What do conscientious people do? Development and validation of the Behavioral Indicators of Conscientiousness (BIC)

Typical assessments of personality traits collapse behaviors, thoughts, and feelings into a single measure without distinguishing between these different manifestations. To address this lack of specification, the current study develops and validates a measure that assesses a number of broad behaviors associated with the personality trait of conscientiousness (the Behavioral Indicators of Conscientiousness; BIC). Findings suggest that the lower-order structure of conscientious behaviors is mostly similar to the lower-order structure in extant trait measures. Furthermore, a daily diary method was used to validate the BIC against frequency counts of conscientious behavior. Overall, the results identify specific behaviors that conscientious individuals tend to perform and highlight possible advantages of this approach over broad trait assessment.     

Might an overweight waitress make you eat more? How the body type of others is sufficient to alter our food consumption

This paper investigates how people's food choices can be shaped by the body type of others around them. Using a professionally constructed obesity prosthesis, we show that the body type of a (confederate) server in a taste test study was sufficient to alter both the quantity (Experiment 1) and specific choices (Experiment 2) participants made but that chronic dieters and non-dieters exhibited opposite effects. While non-dieters ate more snacks when the server was thin, dieters ate more when the server was heavy. Dieters were also more persuaded by a heavy (vs. a thin) server, choosing both a healthy and unhealthy snack more often when she recommended it to them. We suggest these results may be attributable to identification with the server.     

Looking Good and Lying to Do It: Deception as an Impression Management Strategy in Job Interviews

The present study investigated job applicants' use of deception. The study examined applicants' deception on written applications, as well as in a job interview; whether individuals would lie to conform to job requirements; and whether extraversion and self-monitoring are related to lying. Fifty-nine candidates completed an application and interview. After the interview, candidates were informed that they were actually participating in an experiment. They then watched a videotape of their interview and indicated any lies they told. As hypothesized, it was found that applicants lied both on the job applications and during the interview, primarily to appear to conform to job requirements. Furthermore, candidate extraversion was positively correlated with number of lies told, although self-monitoring was unrelated to lying.     

Comparing the Anamnestic Comparative Self-Assessment (ACSA) to a Conventional Happiness Question Without Anchoring

The Anamnestic Comparative Self-Assessment (ACSA) uses a self-anchoring rating scale to measure subjective well-being. Because of its internal frame of reference, ACSA is argued to be less influenced by cultural relativities and psychological traits. We collect survey data in Flanders that contain both a conventional happiness question (CQ) and ACSA. It is the first time that ACSA data are collected in a developed country outside of a clinical setting. In line with previous research, we find that the mean score for ACSA is significantly lower than the mean CQ score and that both scores are positively correlated. Social life (family, relationships, and friends) is cited most when self-anchoring the best period in life, whereas health issues and personal events are most often linked to the worst period in life. These findings add to the idea that the anchors of the ACSA scale are universal. In a simple model, we find that ACSA is determined by two variables that can change over time: being employed and being in a relation. In an extended model, however, ACSA’s insensitivity to socio-demographic variables that are not amenable to change no longer holds and personality traits become important.

     

Family and individual difference predictors of trait aspects of negative interpersonal behaviors during emerging adulthood.

A latent trait-state-occasion (TSO) model (D. A. Cole, N. C. Martin, & J. H. Steiger, 2005) was used to isolate the trait and state components of negative interpersonal behaviors toward a friend or romantic partner during emerging adulthood. Results indicate that variance in negative interpersonal behaviors was due to nearly equal portions of Trait and Occasion factors. Variability in the trait aspects of negative interpersonal behaviors was then predicted by theoretically relevant constructs. In particular, mothers' negative behaviors during adolescence, adolescent core self-evaluations, negative emotionality, and feelings of security in close relationships had independent effects in predicting the enduring aspects of negative interpersonal behaviors. All told, these results indicate that TSO models can be helpful tools for understanding the developmental antecedents of the trait-like aspects of interpersonal processes.     

Is “Generation Me” Really More Narcissistic Than Previous Generations?

ABSTRACT In this commentary, we identify several methodological and conceptual issues that undermine Twenge, Konrath, Foster, Campbell, and Bushman's (this issue) claim that narcissism levels have been rising over the past few decades. Specifically, we discuss (a) the limitations of convenience samples for making inferences about generational differences, (b) our failure to replicate other cross-temporal meta-analytic findings using data from a nationally representative sample, and (c) issues surrounding the interpretation of the Narcissistic Personality Inventory. It is important to consider these issues given the extensive media coverage of Twenge et al.'s claim that today's youth are particularly narcissistic, which has wide-ranging implications for how this generation of young adults views itself and is viewed by society at large.
