Decreasing junk food consumption: A comparison of self-perception theory and reinforcement theory

A behavior reduction procedure based on self-perception theory was developed, and its efficacy was compared to that of a common behavior modification intervention based on traditional reinforcement theory. Following a baseline phase, university students were monetarily reinforced for increasing (in the self-perception condition) or decreasing (in the behavior modification condition) their consumption of junk food. Subsequently, the magnitude of reinforcement was reduced and, finally, the reinforcement contingency was withdrawn. The intervention based on reinforcement theory produced the predicted decrease in junk food consumption while the intervention was in effect, and the postreinforcement intake of subjects in that condition remained below baseline. However, despite an increase in junk food consumption during the intervention phase in the self-perception condition, the hypothesized overjustification effect was not produced. While the results did not support self-perception theory, the data were consistent with an alternative account of the overjustification effect proposed by Williams (1980).This research was partially supported by National Science Foundation Grant SPI8026324 to John F. Kremer and Robert G. Bringle.     

Emotion Dysregulation and Emotional Impulsivity among Adults with Attention-Deficit/Hyperactivity Disorder: Results of a Preliminary Study

Recent reviews argue that emotion dysregulation is an important feature of attention-deficit/hyperactivity disorder (ADHD) and involves a failure to inhibit negative emotions that leads to negative affectively-driven impulsive behavior (i.e., emotional impulsivity). The goal of the current study was to assess (a) whether emotion dysregulation and emotional impulsivity was higher in a group of adults diagnosed with ADHD and (b) if the relationship between core ADHD symptoms (i.e., inattention and hyperactivity-impulsivity) and emotional impulsivity is mediated by emotion dysregulation symptoms. A group of adults with (n?=?18) and without (n?=?23) ADHD completed measures of core ADHD symptoms, emotion dysregulation, and emotional impulsivity. A series of one-way analyses of covariance indicated significant between-group differences in emotion dysregulation and emotional impulsivity when current depression and oppositional defiant disorder ratings were covaried. In addition, the relationship between ADHD symptoms and emotional impulsivity was mediated by emotion dysregulation symptoms. These findings suggest that emotion dysregulation and emotional impulsivity are higher in adults diagnosed with ADHD and that emotion dysregulation symptoms have predictive value beyond core ADHD symptoms.     

The experience of agency in sequence production with altered auditory feedback

When speaking or producing music, people rely in part on auditory feedback - the sounds associated with the performed action. Three experiments investigated the degree to which alterations of auditory feedback (AAF) during music performances influence the experience of agency (i.e., the sense that your actions led to auditory events) and the possible link between agency and the disruptive effect of AAF on production. Participants performed short novel melodies from memory on a keyboard. Auditory feedback during performances was manipulated with respect to its pitch contents and/or its synchrony with actions. Participants rated their experience of agency after each trial. In all experiments, AAF reduced judgments of agency across conditions. Performance was most disrupted (measured by error rates and slowing) when AAF led to an ambiguous experience of agency, suggesting that there may be some causal relationship between agency and disruption. However, analyses revealed that these two effects were probably independent. A control experiment verified that performers can make veridical judgments of agency.     

The well-being outcomes of career guidance

ABSTRACT

The potential for career guidance to impact on well-being has received insufficient attention in the UK. There are both conceptual and empirical reasons to expect that the impacts may be positive, but a lack of evidence directly testing this proposition. Career guidance has commonalities with therapeutic counselling suggesting analogous effects, and it promotes positive engagement in work and learning, which may be associated with health benefits. There are implications for services in reconciling health and employment objectives. However, the promotion of well-being need not imply quasi-clinical ways of working. A call is made for more research and debate in the career guidance community as to the extent and implications of the potentially important relationship between career guidance and well-being.     

The functional independence of trait self-knowledge: Commentary on Sakaki (2007)

In a recent paper, Sakaki (2007) proposed that Klein and Loftus's conclusion that semantic and episodic trait self-knowledge are functionally independent (e.g., Klein, Babey, & Sherman, 1997; Klein & Loftus, 1993a; Klein, Loftus, Trafton, & Fuhrman, 1992b) was based on questionable assumptions and not supported by the available evidence. In this paper we show that Sakaki (2007) has misinterpreted our position on the independence of self-knowledge, omitted mention of large portions of the relevant research at odds with her contention, and conducted her studies with procedures we explicitly warned against due to interpretive ambiguities associated with their use.

Observational Learning and the Role of Confinement in Pigeons: Suppression of Learning as a Function of Observing the Performance of a Conspecific

Observational learning of a successive discrimination problem by pigeons was studied using conspecifics as models responding for either contingent or noncontingent reinforcement. We found that observation of these models was associated with poorer performance on subsequent testing than was shown by a control group that learned without first observing conspecifics' performance. No significant difference was found between subjects without observational experience and another control group that was confined in the observation apparatus and observed an empty chamber only.
