Flow,performance and moderators of challenge-skill balance

The concept of flow is briefly reviewed and several theoretical and methodological problems related to flow research are discussed. In three studies, we attempted to avoid these problems by measuring the experience of flow in its components, rather than operationally defining flow in terms of challenge and skill. With this measure, we tested the assumption that experience of flow substantially depends on the balance of challenge and skill. This assumption could only be partially supported, and, as expected, this relationship was moderated by the (perceived) importance of the activity and by the achievement motive. Furthermore, flow predicted performance in two of the three studies.

Modeling an experiment on construing self and others

In this paper we analyze the results of two repertory grid experiments in which subjects categorized themselves and others on bipolar constructs (Adams-Webber and Rodney, Canadian Journal of Behavioral Sciences, 1983, 15, No 1, 52–59). We attempt to explain these results on the basis of the assumption that the subjects relied upon a special “algebraic processor” for modeling the self and others, previously described by Lefebvre (Journal of Mathematical Psychology, 1980, 22, 83–120; Algebra of conscience: A comparative analysis of western and soviet ethical systems, 1982, Reidel: Dordrecht; Journal of Mathematical Psychology, 1985, 29, 289–310).     

Distinguishing between social reinforcement and social elicitation

The theoretical, procedural, analytic, and interpretive components of Poulson's (1983, Journal of Experimental Child Psychology, 36, 471–489) study were considered in an effort to clarify the distinction between social reinforcement and social elicitation. Contrary to Poulson's contention, DRO was not, and cannot by definition be, a control for reinforcement. More importantly, the speciestypical, social nature of the infant probably reflects the collaborative influence of elicitation and reinforcement. By carefully unravelling these two interacting processes, future conditioning studies might specially enhance our knowledge of early social development.     

Cognitive dissonance as a mechanism in vocational decision processes

This study examined changes in cognitive-dissonance-related variables during the professional training period. Differences in levels and change in satisfaction with career choice, importance of career, certainty of career decision, self-occupational perceptions, general attitude toward career, time since career decision, and past experience were observed when students who left a collegiate professional training program before program completion were compared with those who remained in the program. Data supports the validity of D. Hershenson and R. Roth's (1966, Journal of Counseling Psychology, 13, 368–370) and V. Harren's (1979, Journal of Vocational Behavior, 14, 119–133) theoretical models of vocational decision and the Assessment of Career Decision Making scale.     

On resolving conflicting views of cognitive conflict

F. B. Murray's (Developmental Review, 1983, 3, 54–61) conclusion that a theoretically ambiguous relationship exists between cognitive conflict and Piaget's notion of equilibration was considered. It was suggested that theoretical clarity can be achieved if a distinction is drawn between conflict induction (disequilibrium) and conflict resolution (equilibration). Murray's suggestion that in Piaget's theory internal (cognitive) conflict can be mentally created was disputed. G. N. Cantor's (Developmental Review, 1983, 3, 39–53) concerns about the adequacy of the measures of internal conflict in B. J. Zimmerman & D. E. Blom's (Developmental Review, 1983, 3, 18–38) study due to their independence from external conflict manipulations was discussed. We agreed with Cantor that such findings obviate direct disconfirmation of an internal conflict construct; however, we suggested that evidence of conservation learning in the absence of either external or internal conflict renders Piaget's account less tenable.     

Causal report accuracy: Retrospect and prospect

The paper by M. Sprangers, W. van den Brink, J. van Heerden, and J. Hoogstraten (1987, Journal of Experimental Social Psychology, 23, 302–310) shows that my experiment (P. White, 1980, Psychological Review, 87, 105–112) cannot be interpreted as evidence against the proposal by R. Nisbett and T. Wilson (1977, Psychological Review, 84, 231–259) that accuracy of causal reports cannot be improved by information about internal events. However, the state of all existing literature on this topic is inconclusive because of the failure so far to run an internally valid test. It is suggested that further progress on this topic may depend upon theoretical innovation concentrating on social and practical factors in verbal report generation.     

Why Reading? Because it's there

Three papers (V. A. Mann, Reading skill and language skill. Developmental Review, 1984, 4, 1–15; G. Wolford & C. A. Fowler, Differential use of partial information by good and poor readers. Developmental Review, 1984, 4, 16–35; F. J. Morrison, Reading disability: A problem in rule learning and word decoding. Developmental Review, 1984, 4, 36–47) are critiqued from the standpoint of their adequacy in advancing our understanding of a problem as complex as reading disability. Experimenters should be explicit about their guiding theoretical assumptions, and should think through the relations, if any, between their laboratory tasks and the actual processes of reading. The reading protocol of a dyslexic child is provided, and is interpreted within the frameworks of the Mann, Wolford and Fowler, and Morrison viewpoints.     

Does mindfulness improve inhibitory control in psychotic disorders? A randomized controlled clinical trial

Background/Objective: Impaired Inhibitory Control (IC) is a core feature of psychotic disorders and is related with impaired social functioning in people experiencing psychosis. Despite research showing the benefits of mindfulness over IC in the general population, no study has assessed its effects on IC in psychoses. The aim of our study was to assess the effectiveness of a mindfulness-based intervention combined with integrated rehabilitation treatment in a sample of people diagnosed of psychotic disorders. Method: Fifty-six patients diagnosed with psychotic disorder were recruited and randomly allocated either to integrated rehabilitation treatment or integrated rehabilitation treatment enhanced with 26 mindfulness group sessions. Measures comprised PANSS interview, MAAS scale, and Stroop Color Word Test (SCWT). The primary outcome variable was the performance in the non-congruent trials of the SCWT. Results: There were no differences between groups at baseline. At post-treatment patients allocated to mindfulness group increased their scores in non-congruent trials of SCWT and in MAAS. At post-treatment mindfulness group scored higher than integrated rehabilitation treatment in MAAS. Conclusions: Data suggest that mindfulness added to integrated rehabilitation treatment may improve IC in psychosis. Results are convergent with prior works about the effect of mindfulness over cognitive performance in general population.     

Social status and friendship in peer victimization trajectories

Background/Objective: Most studies have evaluated victimization at a single time point, making it difficult to determine the impact of the time during which an individual is victimized. This longitudinal study aims to examine the differences in the levels of social status (social preference and perceived popularity) and friendship in peer victimization trajectories, and to analyse if there were changes over time in the levels of social status and friendship in each trajectory. Method: The final sample was composed of 1,239 students (49% girls) with ages between 9 and 18 (M = 12.23, SD = 1.73), from 22 schools in southern Spain. Peer nominations were collected. Results: The General Linear Model results associated the highest levels of social preference, perceived popularity and friendship with the sporadic victimization profile and the lowest levels of these dimensions with the stable profile. Conclusions:The results are discussed based on important personal aspects of stable victimization that confirms social rejection, unpopularity, and the low social support that victimization causes. This contribution is discussed in terms of health and social welfare in adolescence.     

Elkind on egocentrism

The purpose of this paper is to respond to D. Elkind's (1985, Developmental Review, 5, 218–226) reply to D. Lapsley and M. Murphy's (1985, Developmental Review, 5, 201–217) critique of the adolescent egocentrism theory. After a reprise of the issues in contention, we address the problem of theoretical consistency and self-other differentiation in Dr. Elkind's (1967, Child Development, 38, 1025–1034) theory. The role of formal operations in the Lapsley and Murphy (1985) account of the imaginary audience and personal fable is revised, and the empirical support for Elkind's theory is reviewed. We conclude that there are good conceptual and empirical grounds for doubting the major assumptions of the adolescent egocentrism theory, and that the Lapsley and Murphy (1985) framework has promise in suggesting theoretical integration with other approaches to the self.     

The pendular mechanism does not determine the optimal speed of loaded walking on gradients

The pendular mechanism does not act as a primary mechanism in uphill walking due to the monotonic behavior of the mechanical energies of the center of mass. Nevertheless, recent evidence shows that there is an important minimization of energy expenditure by the pendular mechanism during walking on uphill gradients. In this study, we analyzed the optimum speed (OPT) of loaded human walking and the pendulum-like determining variables (Recovery R, Instantaneous pendular re-conversion R_int, and Congruity percentage %Cong). Ten young men walked on a treadmill at five different speeds and at three different treadmill incline gradients (0, +7 and +15%), with and without a load carried in their backpacks. We used indirect calorimetry and 3D motion analysis, and all of the data were analyzed by computational algorithms. R_int increased at higher speeds and decreased with increasing gradient. R and %Cong decreased with increasing gradient and increased with speed, independent of load. Thus, energy conversion by the pendular mechanism during walking on a 15% gradient is supported, and although this mechanism can explain the maintenance of OPT at low walking speeds, the pendular mechanism does not fully explain the energy minimization at higher speeds.     

Differential relationships of extraversion,impulsivity, and sociability to study habits

Reanalysis of data on library study habits presented by J. B. Campbell and C. W. Hawley (Journal of Research in Personality, 1982, 16, 139–148) revealed differential utility for the EPI extraversion scale and its components, impulsivity and sociability. Individuals studying in locations that provided greater external stimulation had significantly higher extraversion and impulsivity, but not sociability, scores than individuals studying elsewhere in the library. Impulsivity was more strongly associated than sociability with preferred noise levels, frequency of study breaks, and importance and preferred levels of socializing opportunities, but less strongly associated with preferred levels of crowdedness. Findings are discussed in terms of the interpretation, reliabilities, and theoretical context of the subscales.     

Developing Sexual Agency: Rethinking Late Nineteenth and Early Twentieth Century Theories for the Twenty-First Century

Neo-liberal society asserts that adults should be independent and responsible for themselves, and that children and adolescents should be dependent on their parents. The earlier construction of the concept of adolescence makes this seem obviously true. Yet if we remember that “adolescence” was part of a project of gender, race, and class construction, it becomes easier to ask whether adolescence is a meaningful concept and a stage of life or whether it continues to be a component of an ideology that relies on the construction of “others.” In this chapter, I suggest that adolescence plays the latter role, and that although the naturalization of adolescence is particularly dangerous for groups like queer youth who are at the margins of society, it is dangerous for all young people because it limits sexual agency. This is particularly important because increasingly society requires that young people consider their futures not from the assumption that they will move into well-defined roles, but with the assumption that they will need to define new ways of relating.

The mediating role of trait emotional intelligence,prosocial behaviour,parental support and parental psychological control on the relationship between war trauma,and PTSD and depression

Objectives: This study investigates the relationship between trait emotional intelligence (trait EI), prosocial behaviour, parental support, and parental psychological control on one hand and PTSD and depression symptoms on the other hand after exposure to war-traumatic events among Palestinian children and adolescents in the Gaza Strip. Methods: The sample consists of 1,029 students aged 11–17 year old. Of them 533 (51.8%) were female and 496 (48.2%) were male. The following measures were used in the study: War-Traumatic Events Checklist (W-TECh), Trait Emotional Intelligence Questionnaire – Adolescent Short Form (TEIQue-ASF), prosocial behaviour (as part of the Strengths and Difficulties Questionnaire - SDQ), parental support scale, Parental Psychological Control scale, Post-Traumatic Stress Disorders Symptoms Scale (PTSDSS) and the depression scale. Results: 88.4% (N: 909) experienced personal trauma, 83.7% (N: 861) witnessed trauma to others, and 88.3% (N: 908) have seen demolition of property during the war, mostly by boys. The results also demonstrated that the prevalence of PTSD diagnosis according to DSM-V is 53.5% (N: 549). Further, there is a negative correlation between trait EI and prosocial behaviour in one hand and parental psychological control and PTSD and depression symptoms in the other hand. Likewise, a negative correlation was found between parental support and depression symptoms. Low trait EI and parental psychological control significantly mediated the relationship between exposure to war trauma, and PTSD and depression. In addition, negative parenting factors and low prosocial behavior significantly predicted depression. Conclusion: Trait EI and parental support can be utilized in interventions to empower children and adolescents’ emotional abilities, to strengthen their resilience in facing traumatic event exposure, and thus reduce its effect on PTSD and depression symptoms.     

The Principle of Summation

The principle of Summation, which is a technically sharpened version of the familiar claim that a whole is a sum of its parts, is presented by Peter van Inwagen as a trivial truth. I argue to the contrary, that it is incompatible with the natural assumption that a whole may gain or lose parts non-instantaneously. For, as I show, the latter assumption implies that something can be determinately a whole without being determinately a sum of parts, and this, in turn, indicates the falsity of Summation. I point out that the tension between Summation and the possibility of non-instantaneous gain or loss of parts compels us to rethink the relations between the concepts of whole and sum, and may have far reaching consequences for the mereology of physical objects.

Contemplative withdrawal in the Hellenistic age

I reject the traditional picture of philosophical withdrawal in the Hellenistic Age by showing how both Epicureans and Stoics oppose, in different ways, the Platonic and Aristotelian assumption that contemplative activity is the greatest good for a human being. Chrysippus the Stoic agrees with Plato and Aristotle that the greatest good for a human being is virtuous activity, but he denies that contemplation exercises virtue. Epicurus more thoroughly rejects the assumption that the greatest good for a human being is virtuous activity. He maintains that the greatest good for a human being is the tranquility that virtuous activity always and contemplative activity sometimes brings about.

Testing models for the structure of vocational interests

Several studies aimed at testing the validity of Holland's hexagonal and Roe's circular models of interests showed results on which the null hypothesis of random arrangement can be rejected, and the investigators concluded that the tested models were supported. None of these studies, however, tested each model in its entirety. The present study is based on the assumption that the rejection of the null hypothesis of chance is not rigorous enough. Reanalysis of 13 data sets of published studies, using a more rigorous method, reveals that although the random null hypothesis can in fact be rejected in 11 data sets, the hexagonal-circular model was supported by only 2 data sets and was rejected by 11 data sets. The hierarchical model for the structure of vocational interests (I. Gati, Journal of Vocational Behavior, 1979, 15, 90–106) was submitted to an identical test and was supported by 6 out of 10 data sets, including 4 data sets that rejected the hexagonal-circular model. The predictions of each of the models which tend to be discontinued by empirical data were identified. The implications of the findings for the structure of interests and occupational choice are discussed.     

Psychophysiologic correlates of Type A behavior: Comments on Houston (1983) and Holmes (1983)

On the basis of a literature review, B. K. Houston (1983, Journal of Research in Personality, 17, 22–39) concluded that there is a reliable but relatively weak association between Type A (coronary-prone) behavior and heightened physiologic reactivity. D. S. Holmes (1983, Journal of Research in Personality, 17, 40–47) contends that by failing to take into account dependent measures yielding null results, Houston overestimated the consistency with which A/B differences have been obtained. In the present article, we show that it is critical to take into account the method used to assess Type A behavior. Structured Interview assessments show a more consistent association with reactivity than those based on the Jenkins Activity Survey. We then point out that, for certain physiologic measures, null effects do not necessarily reflect an absence of A/B differences in sympathetic-adrenomedullary activity. Other issues that are discussed include the role of situational parameters in eliciting hyperresponsiveness in Type A's, the problem of evaluating the magnitude and importance of A/B effects, and the need for a more theoretical approach to the study of Type A behavior.
