Influencia del tipo de estimulación en el desarrollo de la automaticidad en las tareas de búsqueda visual

Resumen

En este trabajo, tratamos de comparar el desarrollo de la automaticidad en tareas de búsqueda visual cuando se utiliza como estimulación material familiar y no familiar para el sujeto. Los estímulos no familiares empleados eran equiparables a los caracteres alfanuméricos, únicamente se diferenciaban en el grado de familiaridad. Analizamos si se alcanzan los mismos niveles de automatización en ambos casos, y si los factores que afectaban el desarrollo de la automaticidad eran los mismo. Para ello, diseñamos la misma tarea con estimulación familiar y no familiar, y consideramos los diferentes niveles de consistencia y discriminabilidad. Una vez obtenidos y analizados los resultados encontramos que en ambos casos se alcanzaban los mismos niveles de automatización, aunque cuando el material no era familiar se precisaba mayor cantidad de entrenamiento. Además, en este caso, los aspectos perceptivos como la discriminabilidad entre los objetivos y los distractores incidía en el desarrollo de un procesamiento en paralelo.     

Parental Empowerment: Construct Validity and Reliability of a Dutch Empowerment Questionnaire (EMPO)

In this study, the construct validity and reliability of the Empowerment questionnaire (EMPO) that was developed in Dutch youth care was examined. The 12-item EMPO focuses on measuring parental empowerment in raising their children. The three components of psychological empowerment (intrapersonal, interactional, and behavioral) form the rationale for the EMPO. Non-clinical (n?=?673) and clinical (n?=?1,212) data were used. Construct validity was tested by the factorial structure, measurement invariance, correlations with other instruments (PSQ-S and SDQ), and empowerment differences between the two groups. Reliability was determined by testing the internal consistency and test-retest reliability. The results show that the factorial validity of the EMPO was sufficient to good, the EMPO was measurement invariant for various subgroups, and the EMPO scales were negatively correlated with parenting stress (PSQ-S) and child behavioral problems scales (SDQ). Furthermore, the clinical group was less empowered, and the correlation between parental empowerment and child behavioral problems was stronger in this group. In addition, both groups of parents had relatively high scores on the interactional component. In the clinical group, however, parental scores on the interactional component were less correlated with scores on the intrapersonal and behavioral components. Finally, reliability analyses showed a largely sufficient to good internal consistency and test-retest reliability. The EMPO seems to be an instrument with sufficient to good construct validity and reliability. Further research is recommended regarding the underlying assumptions, other aspects of validity, representativeness, and the way it should be used as a tool by professionals for supporting parental empowerment.     

No body is perfect: the significance of habitual negative thinking about appearance for body dissatisfaction, eating disorder propensity, self-esteem and snacking

Thinking negatively about one's appearance may be a major source of unhappiness. It was investigated whether the habitual quality of negative body image thinking constitutes an additional vulnerability factor, i.e. when such thinking is repetitive and automatic. The cognitive content of negative body image thinking ('what') was distinguished from the habitual occurrence of such thinking ('how'). The mental habit component uniquely predicted explicit as well as implicit body dissatisfaction (the latter measured by an implicit association test) over and above cognitive content. Mental habit also accounted for eating disturbance propensity, low self-esteem and restrained snacking behaviour over and above cognitive content, even when controlled for body dissatisfaction. The habitual component of negative thinking about appearance thus seems a significant body image construct, has discriminant validity against body dissatisfaction, and constitutes a vulnerability factor for feelings of low self-worth and eating disturbance propensity. Implications for intervention strategies, such as mindfulness-based approaches, are discussed.     

Regulating cognitive control through approach-avoidance motor actions

In two studies, the regulatory function of approach-avoidance cues in activating cognitive control processes was investigated. It was hypothesized that avoidance motor actions, relative to approach motor actions, increase the recruitment of cognitive resources, resulting in better performance on tasks that draw on these capacities. In Study 1, error rates on a verbal response mode version of the Stroop task were analyzed. On inconsistent Stroop trials, participants in the avoidance condition made significantly fewer errors than those in the approach condition. In Study 2, performance differences on a task switching paradigm were investigated. Crucially, approach and avoidance motor actions were manipulated within-subjects by alternating between approach and avoidance motor actions on 4 blocks of trials. Temporal switching costs were significantly lower while performing an avoidance, compared to an approach motor action. These results support our hypothesis that avoidance cues, relative to approach cues, lead to improved performance on cognitive control tasks.     

When approach motivation and behavioral inhibition collide: Behavior regulation through stimulus devaluation

In the present article a theory is outlined that explains why and when behavioral inhibition alters stimulus evaluations. In addition, some initial evidence is presented that supports the theory. Specifically, results of three experiments show that refraining from responding to stimuli results in devaluation of these stimuli, but only when these stimuli are positive. These findings suggest automatic behavior-regulation, in terms of devaluation of positive stimuli, in situations in which environmental cues triggering approach (because of the positive valence of the stimulus) run counter to situational demands (cues that elicit behavioral inhibition). Relations of the present research to self-perception, cognitive dissonance, and psychological reactance are discussed.     

Consumption experience of impulse buying in Indonesia: Emotional arousal and hedonistic considerations

Two studies focused on impulsive purchase experiences. Feelings, considerations and ratings of purchase impulsiveness were measured with respect to a recent purchase by means of interviews immediately after the purchase in the shopping environment (Study 1) and through shopping diaries (Study 2). Feelings and considerations were measured by open-ended questions, which yielded a wide range of responses in each category. These responses were subjected to multidimensional scaling. The results demonstrated a high versus low arousal dimension of positive emotions and a hedonic versus utilitarian dimension of considerations. Emotions and considerations were predicted by general impulse-buying tendency, and were related to the experience of impulsive purchases. In Study 2, impulse buying tendency was measured 2 months earlier. Structural equation modelling confirmed a model in which general impulse buying tendency predicts the feelings and considerations in the purchase environment, which in turn, determine the experience of making an impulsive purchase.     

Forewarned is forearmed: Conserving self-control strength to resist social influence

Recent research has shown that resisting persuasion involves active self-regulation. Resisting an influence attempt consumes self-regulatory resources, and in a state of self-regulatory resource depletion, people become more susceptible to (unwanted) influence attempts. However, the present studies show that a forewarning of an impending influence attempt prompts depleted individuals to conserve what is left of their regulatory resources and thus promotes self-regulatory efficiency. As a result, when these individuals are subsequently confronted with a persuasive request, they comply less (Experiments 1 and 3), and generate more counterarguments (Experiment 2) than their depleted counterparts who were not forewarned and thus did not conserve their resources, and they are as able as non-depleted participants to resist persuasion.     

Compulsive Internet Use Among Adolescents: Bidirectional Parent–Child Relationships

Although parents experience growing concerns about their children’s excessive internet use, little is known about the role parents can play to prevent their children from developing Compulsive Internet Use (CIU). The present study addresses associations between internet-specific parenting practices and CIU among adolescents, as well as the bidirectionality of these associations. Two studies were conducted: a cross-sectional study using a representative sample of 4,483 Dutch students and a longitudinal study using a self-selected sample of 510 Dutch adolescents. Results suggest that qualitatively good communication regarding internet use is a promising tool for parents to prevent their teenage children from developing CIU. Besides, parental reactions to excessive internet use and parental rules regarding the content of internet use may help prevent CIU. Strict rules about time of internet use, however, may promote compulsive tendencies. Finally, one opposite link was found whereby CIU predicted a decrease in frequency of parental communication regarding internet use.     

sleep complaints,behavioral characteristics and vital exhaustion in myocardial infarction cases

Abstract

Prodromal symptoms of vital exhaustion and sleep complaints are increasingly being recognized as important risk indicators for myocardial infarction (MI). In this study, the relationships between vital exhaustion, behavioral characteristics, and MI, and between several sleep complaints and MI were investigated. The subjects were 133 male cases with first MI, 192 male hospital controls, and 133 male neighborhood controls. The instruments used were the Maastricht Questionnaire (vital exhaustion), the Life Styles Questionnaire (sleep complaints, coffee consumption, and current smoking), and the Structured Interview (Type A behavior). All sleep complaints, vital exhaustion, Type A behavior, excessive coffee consumption, and current smoking occurred significantly more often in MI-cases. After controlling for these potential confounders, and age, most sleep complaints retained significant associations with MI, in particular often taking naps during the day and waking up in the morning feeling tired and exhausted.     

Coping with dental treatment correlates of dispositional and domain specific monitoring and blunting

Abstract

Relations between coping style and several variables on an intermediary level were studied in a group of dentally anxious patients (N = 68) awaiting dental treatment. Monitoring was found to be positively related to the need of information: General dispositional monitoring was the best predictor of the need of information in case of more distant threat, whereas domain specific monitoring was the best predictor in case of imminent threat. Furthermore. dental trait anxiety was strongly related to early anticipatory tension, degree of anticipatory tension at several moments in time, and tension during treatment as perceived by the dentist, thereby overshadowing the weaker effects of coping style. Domain specific blunting was negatively related to desires for informational adaptations in the waiting room, and to question proneness as perceived by the dentist during treatment. It is concluded that, in order to study further effects of coping style, a sample homogeneous with respect to domain specific anxiety is needed.
