Tonic and phasic orientation in full-term and preterm infants

Thirty-three full-term infants and thirty-eight preterm infants (on average born at 30 weeks gestation) were tested for their latency to turn toward checkered stimulus patterns (phasic orienting or "attention-getting") and for the duration of their initial fixation (tonic orienting or "attention-holding"). Plotted against the logarithm of the subjects' postconceptional age, turning latency fell linearly between 36 and 120 weeks, while fixation time fell abruptly at 53 weeks. Preterm and full-term infants showed the same developmental trends, implying that both of these attentional behaviors are biologically timetabled and that neither is greatly affected by premature extrauterine experience. Unexpectedly, phasic orientation in the first 30 postnatal days was significantly faster in preterm than in full-term infants, and fixation times failed to differ. Despite the necessary functional integration of phasic and tonic orienting in mature visual scanning and attention, the present results suggest an independence in their early postnatal development and that neither is mature at birth.     

Tonic and phasic stimulus control of blood pressure responses using opposing unconditional stimuli

The transswitching paradigm was used in the present study to investigate the effects of tonic (long duration) environmental stimuli paired with opposing unconditional stimuli on human blood pressure. Sixty volunteers participated for two sessions, one week apart. Subjects were presented with a pseudorandom sequence of four trials of red lights (five minutes each) and four trials of blue lights (five minutes each) within each session. All subjects received the cold pressor test during the red lights. During the blue lights, half the subjects received warm water and the other half received a neutral temperature water. Subjects received the presentations of the water in one of three methods: as determined by the experimenter, preceded by a warning signal, or self-administered. The results indicated that conditional and unconditional responses during the red lights were progressive increases in blood pressure. During the blue lights associated with warm water, conditional and unconditional responses were often progressive decreases in blood pressure. The method of administration of the water affected the magnitude of the unconditional responses. Evidence for phasic stimulus control was not as unequivocal as tonic stimulus control. The present results indicated that it is possible to modify blood pressure in two directions (increases and decreases) when two high contrast, opposing unconditional stimuli are presented.     

Conflict over emotional expression: psychological and physical correlates

This study addresses the construct of conflict or ambivalence over emotional expression. Ambivalence is seen as an important mediator in the link between emotional styles and psychological and physical well-being. Using the "personal striving" framework, a questionnaire measure of ambivalent emotional strivings (AEQ) was designed. In Study 1, 292 Ss completed this measure along with questionnaire measures of expressiveness, social desirability, and intense ambivalence. Women scored significantly higher than men on both the AEQ and expressiveness. In Study 2, scores on the AEQ were found to be negatively correlated with self-reported and peer-rated expressiveness. In Study 3, 48 Ss participated in a 21-day study of mood and health. Expressiveness was positively correlated with some measures of well-being and with daily negative affect. Ambivalence was positively correlated with several indices of psychological distress. Although the AEQ correlated with questionnaire measures of physical symptomatology, neither the AEQ nor the expressiveness measures correlated with daily symptom reports. Results support the contention that conflict over emotional expressiveness is a variable worthy of study in its own right, having implications for research on personality and health.     

Processing events: behavioral and neuromagnetic correlates of Aspectual Coercion

Much recent psycho- and neuro-linguistic work has aimed to elucidate the mechanisms by which sentence meanings are composed by investigating the processing of semantic mismatch. One controversial case for theories of semantic composition is expressions such as the clown jumped for ten minutes, in which the aspectual properties of a punctual verb clash with those of a durative modifier. Such sentences have been proposed to involve a coercion operation which shifts the punctual meaning of the verb to an iterative one. However, processing studies addressing this hypothesis have yielded mixed results. In this study, we tested four hypotheses of how aspectual mismatch is resolved with self-paced reading and magnetoencephalography. Using a set of verbs normed for punctuality, we identified an immediate behavioral cost of mismatch. The neural correlates of this processing were found to match effects in midline prefrontal regions previously implicated in the resolution of complement coercion. We also identified earlier effects in right-lateral frontal and temporal sites. We suggest that of the representational hypotheses currently in the literature, these data are most consistent with an account where aspectual mismatch initially involves the composition of an anomalous meaning that is later repaired via coercion.     

The psychophysiology of James Bond: phasic emotional responses to violent video game events

The authors examined emotional valence- and arousal-related phasic psychophysiological responses to different violent events in the first-person shooter video game "James Bond 007: NightFire" among 36 young adults. Event-related changes in zygomaticus major, corrugator supercilii, and orbicularis oculi electromyographic (EMG) activity and skin conductance level (SCL) were recorded, and the participants rated their emotions and the trait psychoticism based on the Psychoticism dimension of the Eysenck Personality Questionnaire--Revised, Short Form. Wounding and killing the opponent elicited an increase in SCL and a decrease in zygomatic and orbicularis oculi EMG activity. The decrease in zygomatic and orbicularis oculi activity was less pronounced among high Psychoticism scorers compared with low Psychoticism scorers. The wounding and death of the player's own character (James Bond) elicited an increase in SCL and zygomatic and orbicularis oculi EMG activity and a decrease in corrugator activity. Instead of joy resulting from victory and success, wounding and killing the opponent may elicit high-arousal negative affect (anxiety), with high Psychoticism scorers experiencing less anxiety than low Psychoticism scorers. Although counterintuitive, the wounding and death of the player's own character may increase some aspect of positive emotion.     

Commitment as psychological process: Theory and pastoral implications

Persons today must devote significant effort to making and remaking personal commitments in a variety of contexts, both interpersonal and social in the larger sense. Therefore, it is important for pastors to acquire an understanding of the basic dynamics of the committing process. It is proposed that this process be viewed as a form of creativity involving four alternating phases, in which regression in the service of the ego allows deep and realistic commitments of self to be formed. Implications for pastoral care are suggested.     

The correlates of psychological health among the Turkish unemployed: Psychological burden of financial help during unemployment

The purpose of this study is to examine the major determinants of psychological health during unemployment. With this in mind, 438 (17% female and 83% male) unemployed individuals were contacted through Turkey's State Employment Office. It was expected that the relationship between duration of unemployment and psychological wellbeing would be nonlinear. Additionally it was hypothesized that perceived social support would moderate the relationship between length of unemployment and psychological health. Further, we suggested that self‐esteem would be related to psychological health and moderate the relationship between length of unemployment and psychological health. The results supported the curvilinearity hypothesis of the relationship between unemployment duration and psychological health as measured by General Health Questionnaire. However, social support was not found to moderate the relationship between unemployment duration and psychological health. The hypothesis that self‐esteem would moderate the relationship between length of unemployment and psychological distress was not supported, although self‐esteem was a strong negative determinant of psychological distress during unemployment. Regression analysis showed that the best predictors of psychological health were self‐esteem, perceived social support and perceived adequacy of financial aid received from relatives. Interestingly, perceived adequacy of the financial aid was negatively related to psychological health. This result was contradictory with the previous literature pointing out that financial aid reduces the effects of poverty due to unemployment. The findings of this study are important since the relationship between unemployment duration and psychological health was nonlinear, indicating that relevant services should be especially careful to intervene to increase social support and self‐esteem during these critical times. The other results and limitations are discussed.     

Electrophysiological correlates of encoding and retrieving emotional events

This study examined the impact of emotional content on encoding and retrieval processes. Event-related potentials were recorded in a source recognition memory task. During encoding, a posterior positivity for positive and negative pictures (250-450 ms) that presumably reflects attentional capturing of emotionally valenced stimuli was found. Additionally, positive events, which were also rated as less arousing than negative events, gave rise to anterior and posterior slow wave activity as compared with neutral and negative events and also showed enhanced recognition memory. It is assumed that positive low-arousing events enter controlled and elaborated encoding processes that are beneficial for recognition memory performance. The high arousal of negative events may interfere with controlled encoding mechanisms and attenuate item recognition and the quality of remembering. Moreover, topographically distinct late posterior negativities were obtained for the retrieval of the context features location and time that support the view that this component reflects processes in service of reconstructing the study episode by binding together contextual details with an item and that varies with the kind of episodic detail to be retrieved.     

The self and depression: Four psychological theories and their potential neural correlates

We review theory and research pertaining to psychodynamic, social, humanistic, and ethological models of the self and depression and examine research into the neurobiological bases of the self and depression. We provide a narrative review of classic and recent empirical evidence pertaining to these four models of the relation of the self to depression as well as exemplar relevant neurobiological research. Evidence stemming from each of the four theories reviewed here shows a robust relationship between deficits in the sense of self and depressive symptoms, as well as increases in depressive symptoms over time. A smaller body of literature has linked one’s sense of self to onsets of depressive episodes. A growing body of literature has linked self-relevant variables to functioning in various prefrontal and cortical midline brain regions as well as emotion and reward processing brain regions which have in turn been linked to depression. Evidence has therefore converged across all four theories and confirmed that a deficit in one’s sense of self confers risk for depression and that there is substantial overlap in the brain areas associated with one’s sense of self and depression.     

Life events and psychological well-being in old age

Abstract

Although life event research has burgeoned in recent years, little attention has been paid to the prevalence of events among the elderly or their relationship to psychological well-being. This paper presents data from a three-wave longitudinal study of community elderly in Aberdeen. Negative life events were highly prevalent among both survivors [N=349) and non-survivors [N=108], but the relatively small differences between the groups indicate that attrition does not seriously affect longitudinal findings. Longitudinal analysis of survivors' data was performed using LISREL and yielded a model with a goodness of fit index of 0.918, demonstrating a close fit between the data and the model. The model parameters indicate that those in poor psychological state were more likely to report serious non-health events than health events, although the latter were more likely than the former to result in a decline in psychological well-being, even after prior psychological state was taken into account. While elderly people with low social integration experienced more severe reactions to life events in the short term than those with high social integration, there were no significant long term effects, even for those reporting highly stressful events. There was no evidence of a sub-group of elderly people lacked into a cycle of serious life events. However life events were not random occurrences; serious health events were more often reported by those with low education while women and those in lower social classes were more likely to report serious non-health events. Overall, long term disruption, directly attributable to life events, was minimal when viewed within the context of the community elderly's stable psychological state.     

Eating attitudes and their psychological correlates among Turkish adolescents

This study examined the eating attitudes and psychological characteristics of Turkish late adolescents. Seven hundred eighty-three university students were administered the Eating Attitudes Test, Rosenberg Self-Esteem Scale, State-Trait Anxiety Inventory, and Social Physique Anxiety Scale. More than one in ten (9.2% of the males and 13.1% of the females) had abnormal eating attitude scores. Chi-square analysis revealed that there were no significant differences in the prevalance of abnormal eating behaviors based on gender. Analysis of covariance indicated that participants who had disturbed eating attitudes had lower self-esteem, higher social physique anxiety, and higher trait anxiety than those who had normal eating attitudes. It was concluded that the prevalence of disturbed eating attitudes was high among these Turkish late adolescents, and that disturbed eating attitudes were related to several psychological characteristics.
