Social desirability bias in diary panels is evident in panelists' behavioral frequency

The purpose was to analyze a large-scale database, a national sample of 1108 heads of households collected by AT&T, to show that behavioral frequencies of the activities of consumer diary panelists may regress toward the population mean during the diary-keeping period given social desirability bias produced by the conditioning effect of keeping diaries. This effect is distinguished from regression toward the mean, a statistical phenomenon reflecting happenstance of extreme initial values. Social desirability bias is demonstrated in two ways-by observing decreasing coefficients of variation over time and by detecting a greater proportion of panelists' behavioral frequencies moving toward the population mean than moving away from it. Both cannot be explained by regression toward the mean. Social desirability bias was manifest only during the early stages of the diary-keeping period and only for activities high in involvement. The presence of social desirability bias in diary panels implies that, when people are subjected to observation, diary observations may be contaminated, leading to the mistaken impression that the population is more homogeneous than it actually is. Thus it is important for researchers to monitor the diary panel carefully to detect social desirability bias when engaged in longitudinal studies.

Social Categorization in Intergroup Contexts: Three Kinds of Self‐Categorization

In reviewing self‐categorization theory and the literature upon which it is based, we conclude that individuals' attempts to form social categories could lead to three kinds of self‐categorization. We label them intergroup categorization, ingroup categorization, and outgroup categorization. We review literature supporting these three types and argue that they can help to explain and organize the existing evidence. Moreover, we conclude that distinguishing these three kinds of self‐categorization lead to novel predictions regarding social identity, social cognition, and groups. We offer some of those predictions by discussing their potential causes (building from optimal distinctiveness and security seeking literatures) and implications (on topics including prototype complexity, self‐stereotyping, stereotype formation, intergroup behavior, dual identity, conformity, and the psychological implications of perceiving uncategorized collections of people). This paper offers a platform from which to build theoretical and empirical advances in social identity, social cognition, and intergroup relations.     

Contextual cueing in preview search

Frequently finding a target in the same location within a familiar context reduces search time, relative to search for objects appearing in novel contexts. This learned association between a context and a target location requires several blocks of training and has long-term effects. Short-term selection history also influences search, where previewing a subset of a search context shortly before the appearance of the target and remaining distractors speeds search. Here we explored the interactions between contextual cueing and preview benefit using a modified version of a paradigm from Hodsoll and Humphreys (Journal of Experimental Psychology: Human Perception and Performance, 31(6), 1346–1358, 2005). Participants searched for a T target among L distractors. Half of the distractors appeared 800 ms before the addition of the other distractors and the target. We independently manipulated the repetition of the previewed distractors and the newly added distractors. Though the previewed set never contained the target, repetition of either the previewed or the newly added context yielded contextual cueing, and the effect was greater when the previewed context repeated. Another experiment trained participants to associate the previewed context with a target location, then disrupted the association in a testing phase. This disruption eliminated contextual cueing, suggesting that learning of the previewed context was associative. These findings demonstrate an important interaction between distinct kinds of selection history effects.

     

THE PAST,PRESENT, AND FUTURE ALL MATTER: HOW TIME PERSPECTIVE IS ASSOCIATED WITH OPTIMISM AND SENSATION SEEKING AMONG YOUNG ADULTS

We used a multidimensional model of time perspective to examine how feelings and thoughts about the past, present, and future were related to optimism and sensation seeking among young adults. The dimensions of time perspective assessed were time feelings, the positive and negative emotions one has about the past, present, and future; time frequency, the amount of thinking about each time period; and time orientation, the relative emphases toward the time periods. Optimism and sensation seeking were self-reported and participants included 463 young adults. Variable-based analyses indicated that reporting more positive and less negative feelings about the time periods or emphasizing the present and future simultaneously were associated with greater optimism. For sensation seeking, boredom susceptibility was especially associated with the time perspective dimensions. Person-centered analyses based on time feelings and time frequency yielded four profiles (i.e., Mindful, Discontent, Bleak, and Indifferent) that were associated with both optimism and sensation seeking.     

A CONSTRUCT MATURES: TIME PERSPECTIVE’S MULTIDIMENSIONAL,DEVELOPMENTAL, AND MODIFIABLE QUALITIES

Human development approaches to time perspective that are life-span and include multiple developmental periods are largely lacking in the literature even though the topic has received wide attention from many scholars. Extant studies have focused on specific age groups or have compared younger and older adults. This introduction addresses these issues and provides on overview of the multidimensional, developmental, and modifiable qualities of time perspective. The four contributions focus on distinct age groups including adolescents, young adults, middle-aged adults, and older adults. The papers comprised several conceptualizations of time perspective, diverse participants, and age-specific outcomes. Collectively, this work sets the stage for the next era of age-related research on time perspective.
