The reactive theory of emotions

Evaluative theories of emotions purport to shed light on the nature of emotions by appealing to values. Three kinds of evaluative theories of emotions dominate the recent literature: the judgment theory equates emotions with value judgments; the perceptual theory equates emotions with perceptions of values, and the attitudinal theory equates emotions with evaluative attitudes. This paper defends a fourth kind of evaluative theory of emotions, mostly neglected so far: the reactive theory. Reactive theories claim that emotions are attitudes which arise in reaction to perceptions of value.     

Effects of cooperative,competitive, and individualistic sets on performance in children's groups

Four instructional sets were employed in a study of task performance in triads of first- (age 7 years) and third-grade (age 9 years) children: promotive (equal rewards given to each participant for 12 trials); individualistic (rewards given in proportion to individual performance for 12 trials); contrient-promotive (winner take all for 6 trials followed by equal rewards for 6 trials); and contrient-individualistic (winner take all for 6 trials followed by proportional rewards for 6 trials). Performance under the promotive condition was superior to performance in the other conditions during the first half of the session. Promotive conditions improved performance during the second half of the session in triads that had received contrient instructions earlier but not to levels reached under continuous promotive conditions. Results are discussed in relation to theories of cooperation and competition.     

Using PPT to account for randomness in perception

According to many theories of decision making, of which signal detection theory is the most prominent, randomness is the main factor responsible for imperfect performance. These theories imply that correcting for attenuation due to randomness should result in perfect scores as long as the participants use nonextreme decision criteria. On the basis of a recent advance termed potential performance theory (Trafimow & Rice, Psychological Review 115:447-462, 2008), we performed auditory and visual detection experiments and corrected the scores for attenuation. Most participants in both experiments tended to perform at a less-than-perfect level, even after their scores were corrected. The findings demonstrate that at least one systematic factor influences detection that is not included in signal detection theory.     

CROSS-CULTURAL SIMILARITIES AND DIFFERENCES ON TWO NEO-PIAGETIAN COGNITIVE TASKS*

Two studies are reported concerning performance differences and similarities across cultures. Pascual-Leone's tests of mental attention/energy (M-power) were administered to Zulu-speaking township children aged from 7 to 12 years. In study 1, the Compound Stimulus Visual Information task (CSVI) was used to determine whether children (N = 292) performed at theoretically predicted levels previously obtained with middle-class Canadian children. In study 2, the children (N = 252) were required to complete the Figural Intersection Test (FIT) four times. Unlike the CSVI, in which learning is controlled by training prior to testing, the FIT assumes basic familiarity with the general test requirements. The purpose of repeated testing was to assess the extent of learning across trials. The results for study 1 indicate that subjects do perform at the predicted levels on the CSVI and have the same M-power as Canadian children. The results for study 2 indicate that the subjects underperform on trial 1 of the FIT but overperform on trial 2 relative to Canadian children. Deux études sont rapportées concernant des différences et des similarités inter-culturelles de performance. Les tests de l'attention mentale/énergie (‘M-power’) de Pascual-Leone ont été administrés à des enfants âgés de 7 à 12 ans provenant de communautés d'expression Zulu. Dans la première étude, la tâche d'information visuelle du stimulus composé (CSVI) a été utilisée pour déterminer si les enfants (N = 292) pouvaient performer aux niveaux prédits théoriquement qui avaient été préalablement observés chez les enfants Canadiens de classe moyenne. Dans la seconde étude, les enfants (N = 252) devaient compléter quatre fois le test de l'intersection des figures (FIT). Contrairement au CSVI, dans lequel l'apprentissage est contrôlé par l'entraînement qui précède l'administration du test, le FIT assume une familiarité de base avec les prérequis généraux du test. Le but visé par la répétition du test était d'évaluer l'étendue de l'apprentissage en fonction des essais. Les résultats de la première étude indiquent que les sujets obtiennent les performances prévues au CSVI et possèdent le měme niveau de ‘M-Power’ que les enfants Canadiens. Les résultats de la seconde étude indiquent que, par comparaison avec les enfants Canadiens, les sujets livrent une performance inférieure au premier essai du FIT, alors qu'ils obtiennent une performance supérieure au second essai.     

Communication accuracy in lower and middle-SES children as a function of task abstraction

The communication encoding performance of lower-SES black, lower-SES white, and middle-SES white children was evaluated when the same familiar stimuli for eliciting communication were presented at three different levels of abstraction. No differences were found between social-class groups. Performance did not differ as a function of level of abstraction. The social group x level of abstraction interaction was not significant. Thus the level of abstraction of the stimuli does not impede the communication encoding performance of lower-SES children. Previous findings of social-class differences in communication accuracy may be an artifact of stimuli that are not equally familiar to all groups.     

What happens during the free-choice period? Evidence of a polarizing effect of extrinsic rewards on intrinsic motivation

The “undermining effect” [e.g., Deci, E. L., Koestner, R., & Ryan, R. M. (1999) A meta-analytic review of experiments examining the effects of extrinsic rewards on intrinsic motivation, Psychological Bulletin, 125(6) 627–668], whereby extrinsic rewards decrease intrinsic motivation, is typically tested using the free-choice paradigm. The arbitrary length of the free-choice period, however, might obscure the process of undermining. We used a foreshortened free-choice period – immediately and after 1 week – to glimpse the process of undermining with 61 college students who engaged in an intrinsically interesting activity under a reward or no-reward condition. Analyses revealed a polarizing effect of extrinsic rewards on intrinsic motivation for the immediate and delayed assessments. We consider this effect in relation to the process of undermining, and suggest a potential personality-based moderator of the effect.     

Factors contributing to the effectiveness of social and nonsocial reinforcers in the discrimination learning of children from two socioeconomic groups

Middle- and lower-class children who had been treated by E in a warm or aloof manner were given a discrimination learning task under one of six conditions forming a 3 × 2 design: three reinforcement types (Verbalintoned, Verbal-nonintoned, or Symbolic) and reinforcement for correct or incorrect responses. In accordance with Zigler's valence theory of social reinforcement, lower-class girls and middle-class children of both sexes tended to perform better when they had previously received warm treatment. No significant differences among the three types of reinforcers occurred in either SE group, thus failing to support the implications of several theories about the relative effectiveness of social and nonsocial reinforcers and tonality factors related to SES.     

Mathematical Proof Theory in the Light of Ordinal Analysis

We give an overview of recent results in ordinal analysis. Therefore,we discuss the different frameworks used in mathematical proof-theory, namely subsystem of analysis including reversemathematics, Kripke–Platek set theory, explicitmathematics, theories of inductive definitions,constructive set theory, and Martin-Löfs typetheory.     

The relationship between non-symbolic multiplication and division in childhood

Children without formal education in addition and subtraction are able to perform multi-step operations over an approximate number of objects. Further, their performance improves when solving approximate (but not exact) addition and subtraction problems that allow for inversion as a shortcut (e.g., a?+?b???b?=?a). The current study examines children's ability to perform multi-step operations, and the potential for an inversion benefit, for the operations of approximate, non-symbolic multiplication and division. Children were trained to compute a multiplication and division scaling factor (*2 or /2, *4 or /4), and were then tested on problems that combined two of these factors in a way that either allowed for an inversion shortcut (e.g., 8*4/4) or did not (e.g., 8*4/2). Children's performance was significantly better than chance for all scaling factors during training, and they successfully computed the outcomes of the multi-step testing problems. They did not exhibit a performance benefit for problems with the a*b/b structure, suggesting that they did not draw upon inversion reasoning as a logical shortcut to help them solve the multi-step test problems.     

Learning potential and anxious tendency: Test anxiety as a bias factor in educational testing

Abstract

Contrary to conventional educational testing, in so-called dynamic assessment subjects are allowed to consult help during testing or are offered prior training. The differential results of both testing procedures are sometimes ascribed to the idea that dynamic tests reflect the breadth of the zone of proximal development on top of independent achievement. Alternative explanations claim that conventional tests are more strongly biased towards various characteristics of persons, which have a negative influence on performance, when compared to dynamic tests. In this study, it was hypothesised that static as well as dynamic assessment is biased towards anxious tendencies of subjects, but the former more strongly than the latter. In order to investigate this supposition, the performance of subjects on dynamic and static tests was systematically compared and related to measures of test anxiety in a longitudinal experiment. In the experiment, repeated measures of independent mathematics achievement as well as mathematics learning potential were gathered among students of secondary education in the Netherlands. Prior to every mathematics test, subjects filled out a test anxiety questionnaire. After every mathematics test, subjects filled out a general state anxiety questionnaire. The participating subjects were students from secondary education, either preparing for higher vocational training or university, aged approximately 15 years on average.

The results of the experiment showed that lack of self-confidence is an important constituent factor of test anxiety, apart from worry and emotionality. The data supported the assumption that such testing procedures are less biased towards anxiety than conventional tests, but it was not established that dynamic testing procedures render results that are not biased by test anxious tendencies.     

Neuropsychological complications of insulin dependent diabetes in children

Previous research suggests that children with insulin dependent diabetes (IDDM) show selective impairments on neuropsychological tests, with those developing IDDM before 5 years of age appearing to be the most affected. The effect of hypoglycaemia on the developing brain has been suggested as a possible risk factor as has the disruptive effect of chronic hyperglycaemia on myelinisation. A cohort of children (n = 124) with newly diagnosed IDDM, managed at The Royal Children's Hospital, Melbourne has been assembled and evaluated 3 months post diagnosis on standardised tests of general intelligence, attention, memory, new learning, executive functions, and educational achievement. The performance of the children with IDDM has been compared with that of a demographically representative control group (n = 129) of healthy children. At this baseline assessment, the findings strongly support the hypothesis that the neuropsychological and educational profiles of newly diagnosed children are not different from that of controls early in the course of the illness. Both groups will be reassessed 2 and 5 years after the initial evaluation when it is hypothesised that children with diabetes will perform more poorly. Parameters of the illness, such as age of onset, major metabolic crises, and history of glycaemic control will be related to the test performance of the children with IDDM to identify specific risk factors for neuropsychological and educational sequelae in that population.     

Comparing Fixed-Point and Revision Theories of Truth

In response to the liar’s paradox, Kripke developed the fixed-point semantics for languages expressing their own truth concepts. (Martin and Woodruff independently developed this semantics, but not to the same extent as Kripke.) Kripke’s work suggests a number of related fixed-point theories of truth for such languages. Gupta and Belnap develop their revision theory of truth in contrast to the fixed-point theories. The current paper considers three natural ways to compare the various resulting theories of truth, and establishes the resulting relationships among these theories. The point is to get a sense of the lay of the land amid a variety of options. Our results will also provide technical fodder for the methodological remarks of the companion paper to this one.     

The effect of extrinsic constraints on children's creativity while using a computer

Abstract:

Two studies were conducted to examine the impact of extrinsic constraints on children's performance while using a computer. Open‐ended tasks were presented and possible differential effects of rewards and evaluations imposed by human (experimenter) and non‐human (computer) sources were explored in relation to product creativity, motivation, and affective response. Both studies provide support for the hypothesis that reward and evaluation will undermine creativity and motivation, even when a computer serves as the source of these constraints. In addition, a developmental trend emerged with older children being far more adversely affected than their younger counterparts. The theoretical and applied significance of these results are discussed.     

Attentional deficits of learning-disabled children: Effects of rewards and practice

This study investigated the effects of rewards and practice on the attentional task performance of learning-disabled (LD) and normally achieving children. Contingent feedback and rewards resulted in faster but less accurate performance by the LD children. Despite the speed-accuracy trade-off, the LD children still responded more slowly than the controls. However, limited practice on the tasks resulted in significantly improved performance, such that the groups performed similarly. Poorer performance of LD children on their first encounter with laboratory measures of attention may be due to inefficient strategies rather than to actual deficits in ability to attend.This paper is based on the author's dissertation. I gratefully acknowledge the assistance of Nancy Ponzetti-Dyer, Susan Shapiro, and Duane Kemp in the data collection, and of Raymond Romanczyk and two anonymous reviewers for comments on a draft of this article.     

Effects of Backpack Carriage on Dual-Task Performance in Children During Standing and Walking

Primary school children perform parts of their everyday activities while carrying school supplies and being involved in attention-demanding situations. Twenty-eight children (8–10 years old) performed a 1-legged stance and a 10 m walking test under single- and dual-task situations in unloaded (i.e., no backpack) and loaded conditions (i.e., backpack with 20% of body mass). Results showed that load carriage did not significantly influence children's standing and walking performance (all p > .05), while divided attention affected all proxies of walking (all p < .001). Last, no significant load by attention interactions was detected. The single application of attentional but not load demand negatively affects children's walking performance. A combined application of both did not further deteriorate their gait behavior.     

Comparing rapid assessments of delay discounting with real and hypothetical rewards in children

Recent advances in assessment methodology have resulted in a highly efficient procedure for obtaining delay discounting rates for adults: a 5‐trial adjusting delay task (ADT‐5) examining intertemporal choice for hypothetical rewards. The low participant burden of this task makes it potentially useful for children, with whom delay discounting research is relatively limited. However, it is unknown whether results from this task match choice for real rewards. The present study assessed delay discounting for real and hypothetical monetary rewards using a modified ADT‐5 with 9 children admitted to a psychiatric day treatment program. Participants completed up to 3 tasks with each reward type in alternating order. No difference in discounting rate, via log(k), was observed between the first task of each reward type. This finding was replicated across subsequent tasks for the subset of participants (n = 6) who completed all 6 tasks. However, delay discounting of real and hypothetical rewards was not found to be statistically equivalent. These results suggest that a modified ADT‐5 using hypothetical rewards may be a viable option for assessing delay discounting in children with psychiatric diagnoses, but additional research is needed to explicitly examine whether hypothetical and real rewards are discounted equivalently in this population.     

A Two-Year Longitudinal Study of Neuropsychological and Cognitive Performance in Relation to Behavioral Problems and Competencies in Elementary School Children

Despite interest in early neuropsychological status as a possible contributor to children's behavioral development, prospective longitudinal investigations of neuropsychological measures in relation to later behavioral outcomes in childhood are few. A 2-year longitudinal study in a nonselected childhood sample is reported. The study tested the influence of early neuropsychological performance (verbal fluency, mental inhibitory control, and visual spatial ability) on later childhood behavioral problems and social competency. Regular education children (n = 235) were assessed at three time points 1 year apart. To control for autocorrelation of outcome measures, Time 1 behavior was partialed while testing the effects of Time 1 neuropsychological scores on Time 3 outcome. To control for autocorrelation of neuropsychological scores, Time 2 scores were partialed while testing the predictive effect of Time 1 scores on Time 3 outcome. Both sets of regression models suggested modest but statistically significant effects for inhibitory control and verbal fluency, but not IQ, reading, or visual spatial ability, on behavioral outcome. Study results are consistent with a modest causal effect of selected neuropsychological skills on later behavioral adjustment. The findings support theories that implicate subtle neuropsychological dysfunction in the development of behavioral problems in childhood.     

Retrieval practice in motor learning

In this study we sought to determine whether testing promotes the generalization of motor skills during the process of encoding and/or consolidation. We used a dynamic arm movement task that required participants to reproduce a spatial-temporal pattern of elbow extensions and flexions with their dominant right arm. Generalization of motor learning was tested by the ability to transfer the original pattern (extrinsic transformation) or the mirrored pattern (intrinsic transformation) to the unpractised left arm. To investigate the testing effects during both encoding and consolidation processing, participants were administered an initial testing session during early practice before being evaluated on a post-practice testing session administered either 10 min (Testing-Encoding group) or 24 hr apart (Testing-Consolidation group), respectively. Control groups were required to perform a post-practice testing session administered after either a 10-min (Control-Encoding group) or 24-hr delay (Control-Consolidation group). The findings revealed that testing produced rapid, within-practice skill improvements, yielding better effector transfer at the 10-min testing for the Testing-Encoding group on both extrinsic and intrinsic transformation tests when compared with the Control-Encoding group. Furthermore, we found better performance for the Testing-Consolidation group at the 24-hr testing for extrinsic and intrinsic transformations of the movement pattern when compared with the Control-Consolidation group. However, our results did not indicate any significant testing advantage on the latent, between-session development of the motor skill representation (i.e., from the 10-min to the 24-hr testing). The testing benefits expressed at the 10-min testing were stabilised but did not extend during the period of consolidation. This indicates that testing contributes to the generalisation of motor skills during encoding but not consolidation.     

Help,Likability, and Social Influence1

What factors affect an aid-giver's perceived helpfulness and likeability and the amount of positive and negative social influence he is able to exert? In experiment I, subjects performing a difficult task expected or did not expect to receive help which they subsequently received or did not receive. No significant differences were found in reactions to the aid-giver in the two expectancy confirmation conditions. However, reactions were markedly different in the two disconfirmation conditions-very positive when unexpected help was received and very negative when expected help was not received. The two hypothesized main effects were found (p < .05) on the negative social influence, or counter-conformity, measure. In experiment II, the perceived nature of the task was varied. Subjects received or did not receive unexpected help on a relatively unimportant task which yielded only extrinsic rewards or on an intelligence test which yielded only intrinsic, ego-rewards. This time, social influence and counter-conformity measures both showed predicted interaction effects (p < .05), while attitudinal measures did not.     

A cross‐syndrome study of the differential effects of sleep on declarative memory consolidation in children with neurodevelopmental disorders

Sleep plays an active role in memory consolidation. Because children with Down syndrome (DS) and Williams syndrome (WS) experience significant problems with sleep and also with learning, we predicted that sleep‐dependent memory consolidation would be impaired in these children when compared to typically developing (TD) children. This is the first study to provide a cross‐syndrome comparison of sleep‐dependent learning in school‐aged children. Children with DS (n = 20) and WS (n = 22) and TD children (n = 33) were trained on the novel Animal Names task where they were taught pseudo‐words as the personal names of ten farm and domestic animals, e.g. Basco the cat, with the aid of animal picture flashcards. They were retested following counterbalanced retention intervals of wake and sleep. Overall, TD children remembered significantly more words than both the DS and WS groups. In addition, their performance improved following night‐time sleep, whereas performance over the wake retention interval remained stable, indicating an active role of sleep for memory consolidation. Task performance of children with DS did not significantly change following wake or sleep periods. However, children with DS who were initially trained in the morning continued to improve on the task at the following retests, so that performance on the final test was greater for children who had initially trained in the morning than those who trained in the evening. Children with WS improved on the task between training and the first retest, regardless of whether sleep or wake occurred during the retention interval. This suggests time‐dependent rather than sleep‐dependent learning in children with WS, or tiredness at the end of the first session and better performance once refreshed at the start of the second session, irrespective of the time of day. Contrary to expectations, sleep‐dependent learning was not related to baseline level of performance. The findings have significant implications for educational strategies, and suggest that children with DS should be taught more important or difficult information in the morning when they are better able to learn, whilst children with WS should be allowed a time delay between learning phases to allow for time‐dependent memory consolidation, and frequent breaks from learning so that they are refreshed and able to perform at their best.
