Nutritional habits and motivations to eat after a palatable pre-load

A representative sample of college students was surveyed about nutritional habits and motivations to eat. Females were more likely to report dieting, being overweight, reading nutritional labels, eating healthy meals, as well as hungering for and consuming lower fat foods compared to males. Males reported a greater hunger for and consumption of candy bars compared to females. Thus, females may not be as ambivalent about eating sweet or higher fat foods as previously suggested. The experimental manipulation involved exposing subjects to either candy before the survey, candy with the survey, or just the survey with no candy exposure. Females exposed to the candy preload indicated an increased hunger for fruits and vegetables compared to female controls. Portions of this research have been presented at the 1999 annual meeting of the Eastern Psychological Association in Providence, RI.

Parental Influences on Memories of Parents and Friends

The authors evaluated the role parent–child relationship quality has on two types of memories, those of parents and those of friends. Participants were 198 Italian university students who recalled memories during 4 separate timed memory-fluency tasks about their preschool, elementary school, middle school, high school and university years. Half were instructed to recall memories involving parents and the remainder memories involving friends. Moreover, parent–child relationships were assessed by the Network of Relationships Inventory (NRI; W. Furman & D. Buhrmester, 1985) and Adolescents’ Report of Parental Monitoring (D. M. Capaldi & G. R. Patterson, 1989). Results showed that men with positive parent–son relationships had more memories of parents and more affectively positive memories of friends, supporting a consistency model positing similarity between parent–child relationships and memories of friends. Women with positive parental relationship quality had more affectively positive memories of parents but for friends, positive relationship quality only predicted positive memories when young. At older ages, especially middle school-aged children, negative parent–daughter relationships predicted more positive memories of friends, supporting a compensatory model. The gender of parent also mattered, with fathers having a more influential role on affect for memories of friends.     

When disfluency is—and is not—a desirable difficulty: The influence of typeface clarity on metacognitive judgments and memory

There are many instances in which perceptual disfluency leads to improved memory performance, a phenomenon often referred to as the perceptual-interference effect (e.g., Diemand-Yauman, Oppenheimer, & Vaughn (Cognition 118:111–115, 2010); Nairne (Journal of Experimental Psychology: Learning, Memory, and Cognition 14:248–255, 1988)). In some situations, however, perceptual disfluency does not affect memory (Rhodes & Castel (Journal of Experimental Psychology: General 137:615–625, 2008)), or even impairs memory (Glass, (Psychology and Aging 22:233–238, 2007)). Because of the uncertain effects of perceptual disfluency, it is important to establish when disfluency is a “desirable difficulty” (Bjork, 1994) and when it is not, and the degree to which people’s judgments of learning (JOLs) reflect the consequences of processing disfluent information. In five experiments, our participants saw multiple lists of blurred and clear words and gave JOLs after each word. The JOLs were consistently higher for the perceptually fluent items in within-subjects designs, which accurately predicted the pattern of recall performance when the presentation time was short (Exps. 1a and 2a). When the final test was recognition or when the presentation time was long, however, we found no difference in recall for clear and blurred words, although JOLs continued to be higher for clear words (Exps. 2b and 3). When fluency was manipulated between subjects, neither JOLs nor recall varied between formats (Exp. 1b). This study suggests a boundary condition for the desirable difficulty of perceptual disfluency and indicates that a visual distortion, such as blurring a word, may not always induce the deeper processing necessary to create a perceptual-interference effect.     

The drug‐crime nexus among adolescents and their peers

The purpose of this paper is to determine the nature of the drug‐crime relationship by exploring the influence of friend behaviors on both adolescent delinquent and substance using behavior. The sample consists of 1381 adolescents evenly divided by gender into three age groups (12, 15 and 18 years old). In general, there is an increase in intensity of substance use from the youngest to the oldest age level with male and female levels being similar within each age group. There are both age and gender differences when examining delinquent behavior. There is a relationship between adolescent drug use and crime (especially among males), however this relationship is relatively modest. In addition, while friends’ behavior is a very strong predictor of the same type of behavior in subjects, there are no strong crossover relationships. Thus, the hypothesis that both types of behavior are part of a specific deviant peer subculture is not confirmed.     

Processing Illness Information: The Role of Disease Prototypes

Recently Bishop and Converse (1986) proposed that information about physical symptoms is interpreted by relating those symptoms to preexisting disease prototypes. The two present studies further examined this formulation by testing hypotheses concerning the speed of processing symptom information as well as associations made to sets of physical symptoms as a function of prototypicality. As predicted, Experiment 1 showed that response time to highly prototypical symptom sets was significantly shorter than that for symptom sets containing irrelevant symptoms. Also as predicted, the results of Experiment 2 showed significant differences in the associations made by experiment participants to symptom sets as a function of the prototypicality of the symptoms in those sets. Participants made more category-based associations to highly prototypical symptom sets than to those lower in prototypicality but made more associations to individual symptoms for symptom sets low in prototypicality. Implications for the prototype hypothesis and for understanding the processing of illness information are discussed.     

Temporal Aspects of Team Cognition: A Case Study on Concerns Sharing Within Basketball

This case study investigated team cognition in basketball. The focus was on how concerns in a real match situation were shared among teammates and how the sharedness evolved. The activity of five basketball players (M age = 17.60, SD = 0.89) was studied. The data were collected and processed according to a procedure defined for course-of-action analysis (Theureau, 2003). The results indicated that the instances when all the teammates shared the same typical concern were relatively rare, but temporal analysis revealed two kinds of convergence phenomena (simultaneous and progressive). In conclusion, shared understanding emerged within this team as essentially “local sharing of understanding.”
