Emotional state and the detection of change in facial expression of emotion

A new method is presented for examining effects of emotion in the detection of change in facial expression of emotion. The method was used in one experiment, reported here. Participants who were induced to feel happiness, sadness, or neutral emotion, saw computerized 100‐frame movies in which the first frame always showed a face expressing a specific emotion (e.g. happiness). The facial expression gradually became neutral over the course of the movie. Participants played the movie, changing the facial expression, and indicated the frame at which the initial expression was no longer present on the face. Emotion congruent expressions were perceived to persist longer than were emotion incongruent expressions. The findings are consistent with previous findings documenting enhanced perceptual processing of emotion congruent information. The value of the current technique, and the types of everyday situations that it might model are discussed. Copyright © 2000 John Wiley & Sons, Ltd.     

Issues in the treatment of depressed children

Basic research into the cognitive, behavioral, familial, and physiological disturbances associated with depressive disorders during childhood is reviewed. Implications for the development of a treatment program are discussed and a comprehensive treatment model is proposed. The proposed model includes intervention strategies for the child, parents, family, and school. The child component consists of intervention strategies for the affective, cognitive, behavioral, and physiological disturbances that are evident from the existing research. The parent training component is designed to address disturbances in parenting due to cognitive disturbances and skills deficits. The family therapy component emphasizes changing interaction patterns that communicate schema-consistent maladaptive interactions. A school consultation component is proposed in which school personnel support the skills training through prompting use of the skills and reinforcement of the use of the coping skills.     

Marx and Exploitation

The discussion of the adequacy of Karl Marx's definition of exploitation has paid insufficient attention to a prior question: what is a definition? Once we understand Marx as offering a “reference-fixing definition in a model” we will realise that it is resistant to certain objections. A more general analysis of exploitation is offered here and it is suggested that Marx's own definition is a particular instance of the general analysis which makes a number of controversial moral assumptions.     

Age of acquisition affects object recognition: evidence from visual duration thresholds

The impact of age of acquisition (AoA) on object recognition was explored in three experiments measuring visual duration threshold (VDT) for the identification of pictures labelled with early and late acquired names. Participants viewed briefly displayed images preceded and followed by a pattern mask. The minimum display duration required for correct identification was shorter for pictures labelled with early names than for those labelled with late names. In Experiments 2 and 3 we explored the effects of two forms of visual degradation on VDT for pictures with early and late acquired names. Both degradation by superimposed visual elements, and degradation by contrast reduction extended VDT, but only the former interacted with AoA. We conclude that both AoA and degradation by superimposed visual elements affect the efficiency of visual object recognition, but only degradation by contrast and not AoA affects the efficiency of earlier pre-recognition processes.     

Religiosity and treatment response to antidepressant medication: a prospective multi-site clinical trial

The present study examined the relationship between religiosity/spirituality and treatment response to antidepressant medication (citalopram). One-hundred and forty-eight Caucasian and African-American adults with uncomplicated major depression were treated with citalopram (20–60?mg/day) over an eight-week period in a prospective multi-site clinical trial. Treatment response was assessed weekly with the Hamilton Rating Scale for Depression. Religiosity (i.e., religious behaviours) and spirituality (i.e., spiritual well-being) were assessed at week 3. No significant associations between spirituality and treatment response were found; however, there was a strong curvilinear relationship between religiosity and treatment response. Compared to lower or higher levels of religiosity, a moderate level of religiosity was significantly associated with a higher likelihood of remission and greater reduction in severity of depression. This association was independent of social support, ethnicity, gender, education, and baseline depression severity. A moderate amount of religiosity appears to be independently associated with an enhanced treatment response to citalopram.     

Toward a comprehensive model of face impressions: What we know,what we do not,and paths forward

A person's impression of another depends upon three sources of variance. The characteristics of the target, the characteristics of the perceiver, and the interplay between the two. Researchers have dedicated different amounts of study to these three sources of variance, and therefore they differ in how well they are understood. The present work will first review the portions of the face impression process that are understood well, then identify and discuss portions of the process less well understood. We will then question to what extent the current state of knowledge will generalize to novel targets and populations. Finally, we will review several modeling approaches that can accommodate relatively unexamined yet important sources of variance in impression formation, suggesting a clear path forward toward a comprehensive understanding of face impressions.     

Production deficits in aphasia: A voice-onset time analysis

An experimental study was conducted to examine phonetic and phonemic deficits in the speech production of aphasics. Subjects included four Broca's aphasics, four Conduction aphasics, five Wernicke's aphasics, one nonaphasic dysarthric patient, and four normal controls. The subjects read a list of words containing word-initial stop consonants which were subsequently measured acoustically for voice-onset time. The results showed that Broca's aphasics exhibit a more severe production disorder than Conduction aphasics who in turn exhibit a more severe disorder than Wernicke's aphasics, in accord with clinical observations. In addition, although Broca's aphasics produced both phonetic and phonemic errors, the results showed that they have a pervasive phonetic disorder which affects their correct target productions as well as the total number of phonetic errors produced. This deficit however seems to be a speech deficit rather than a low-level motor control problem. In contrast, the Wernicke's aphasics show a deficit characterized by isolated phonemic mistargeting errors. Finally, the pattern of productions for the Conduction aphasics indicates that some patients show a predominantly phonetic disorder similar to the Broca's aphasics and others show predominantly a phonemic disorder similar to the Wernicke's aphasics.     

The Belief in Good Luck Scale

The construction and properties of the Belief in Good Luck (BIGL) Scale are described. Three studies provide evidence that reliable individual differences exist with respect to beliefs about luck. Some individuals maintain an irrational view of luck as a somewhat stable force that tends to influence events in their own favor, while others seem to hold the more rational belief that luck is random and unreliable. Further, these beliefs showed a considerable amount of stability over time. The BIGL was significantly related to locus of control (primarily to a chance subscale), but other evidence suggested these constructs were distinct. Belief in good luck was not related to general optimism, academic pessimism, self-esteem, desire for control, or achievement motivation. There was also evidence that belief in good luck was distinct from feeling fortunate or generally satisfied with one's life. Ethnic group differences were observed for the BIGL scale, showing that Asian-Americans were more likely to endorse superstitious beliefs about luck than non-Asians. Finally, the BIGL scale was shown to predict positive expectations for the outcome of everyday situations that are typically associated with luck. This is generally in agreement with previous findings suggesting that people who believe in personal good luck react to lucky events by becoming more positive about the likelihood of future success (Darke & Freedman, 1997). In general, it is suggested that irrational beliefs about luck can serve as a source of positive expectations for the outcome of future events.
