An enactivist approach to treating depression: cultivating online intelligence through dance and music

Phenomenology and the Cognitive Sciences - This paper utilizes the enactivist notion of ‘sense-making’ to discuss the nature of depression and examine some implications for treatment....     

Mathematics of forgiveness

This study was aimed at determining the integration rule--summation or averaging--underlying the forgiveness schema. The main reason for distinguishing between these structures is that they have very different practical implications regarding the influence of various factors specific to each case on the propensity to forgive. In a summative model, the impact of the different factors and the direction of the effects are constant. For example, the presence of apologies always is a positive element even when these apologies assume a very weak form. By contrast, in an averaging model, the apologies can be a positive or a negative element depending on the current level of propensity to forgive and the form of the apologies. Two experiments were conducted using the functional theory of cognition framework. Experiment 1 applied the missing information test. Experiment 2 applied the credibility of information test. In both experiments, clear evidence favored a summative rule for judging willingness to forgive from circumstantial information such as presence or absence of intent, presence of absence of apologies, and degree of cancellation of consequences.     

Are high school students accurate or clueless in estimating substance use among peers?

The purpose of this study was to assess adolescents' estimations of the prevalence of alcohol and other drug use and to examine the consistency between these estimations and reported use. A survey was administered to 223 students in three northwestern U.S. high schools. Results showed that students in each of the three high schools grossly overestimated the prevalence of substance use when compared to self-reports of use. Still, students were not entirely clueless about the relative normativeness of substance use when comparing estimates and rates of use among the three schools. The school with the highest estimated prevalence of a particular substance use behavior generally also had the highest self-reported use of that same substance. These findings imply the need for high school personnel to provide students with accurate information about the actual prevalence of substance use within each school.     

Assessment of dysfunctional beliefs in borderline personality disorder

This study had two aims: to test the hypothesis that borderline personality disorder (BPD) patients hold numerous dysfunctional beliefs associated with a variety of Axis II disorders, and to construct a BPD belief scale which captures these beliefs. Beliefs were measured using the Personality Belief Questionnaire (PBQ) which is designed to assess beliefs associated with various personality disorders, although not specifically BPD. Eighty-four BPD patients and 204 patients with other personality disorders (OPD) were randomly split into two study samples. Fourteen PBQ items were found to discriminate BPD from OPD patients in both samples. These items came from the PBQ Dependent, Paranoid, Avoidant, and Histrionic scales and reflect themes of dependency, helplessness, distrust, fears of rejection/abandonment/losing emotional control, and extreme attention-seeking behavior. A BPD beliefs scale constructed from these items showed good internal consistency and diagnostic validity among the 288 study patients. The scale may be used to assist in diagnosis and cognitive therapy of BPD.     

Strategic attention deployment for delay of gratification in working and waiting situations

Two studies examined whether the detrimental effects of attention to rewards on delay of gratification in waiting situations holds-or reverses-in working situations. In Study 1, preschoolers waited or worked for desired delayed rewards. Delay times increased when children worked in the presence of rewards but, as predicted, this increase was due to the distraction provided by the work itself. not because attention to rewards motivated children to sustain work. Analysis of spontaneous attention deployment showed that attending to rewards reduces delay time regardless of the working or waiting nature of the task. Fixing attention on rewards was a particularly detrimental strategy regardless of the type of task. Study 2 showed that when the work is not engaging, however, attention to rewards can motivate instrumental work and facilitate delay of gratification as long as attention deployment does not become fixed on the rewards.     

Two-year-olds' search strategies and visual tracking in a hidden displacement task

Children younger than 3 years have difficulty with search tasks that involve hidden displacement. Partial visual information was provided about a ball's path as it moved toward a hiding place. Children (2.0 and 2.5 years old) saw a ball rolling down a ramp placed behind a transparent screen with 4 opaque doors. A wall, placed on the ramp and directly behind 1 of the doors, protruded above the screen and stopped the ball. Children were asked to find the ball. The transparency of the screen permitted visual tracking of the ball between the doors, but its final resting place was obscured. Both age groups were equally proficient at tracking the ball as it rolled behind the screen, but the 2.5-year-olds were more likely to reach to the correct door. Looking behavior was related to errors in the younger group in that tracking that stopped short or continued past the correct door was associated with incorrect choices.     

Dual-task attention deficits in dysphoric mood

The attentional functioning of nondysphoric, mildly dysphoric, and moderately to severely dysphoric college students was tested using the attentional blink (AB) paradigm. These groups performed equally well at reporting a single target appearing in a rapidly presented stream of stimuli. All groups showed an AB, with report sensitivity for a 2nd target being reduced when the 2 targets were presented less than 0.5 s apart. Nondysphoric and mildly dysphoric participants showed the same size ABs, but the ABs for moderately to severely dysphoric participants were larger and longer. As predicted, the results showed that moderately to severely dysphoric individuals have attentional impairments. These impairments, however, were evident only in the more demanding dual-task condition.     

The impact of cross-training on team effectiveness

The authors examined the role of cross-training in developing shared team-interaction mental models, coordination, and performance in a 2-experiment study using computer simulation methodology (for Experiment 1, N = 45 teams; for Experiment 2, N = 49 teams). Similar findings emerged across the 2 experiments. First, cross-training enhanced the development of shared team-interaction models. Second, coordination mediated the relationship between shared mental models and team performance. However, there was some inconsistency in the findings concerning the depth of cross-training necessary for improving shared mental models. Results are discussed in terms of the impact of different levels of cross-training on team effectiveness.
