A case of prosopagnosia with some preserved covert remembrance of familiar faces

This paper presents the detailed analysis of a case of prosopagnosia in a 54-year-old male farmer following bioccipital vascular disease. In-depth clinical investigations confirmed the diagnosis of prosopagnosia and revealed the absence of any associated defect, except for a slight aspecific disturbance of the short-term memory. Further study of this case indicated that the trouble was not concerned with the class of complex visual stimuli, was not even concerned with facial expressions or unknown faces, was not a perceptual defect, but was related mainly to the operation of individualization. The memory hypothesis was thus retained and supported. Moreover, exploration of the difficulty indicated that the deficiency was limited to defective access to conscious information concerning faces and information associated with these faces (name, context, etc.), effectively stored in memory.     

The Accuracy of the DSM-IV Pain Disorder and the ICD-10 Persistent Somatoform Pain Disorder in Chronic Pain Patients

Objectives. In this investigation we studied the relationships between different psychological relevant subgroups and the presence of different psychosomatic symptoms in a sample of chronic pain patients, testing the accuracy of the DSM- and ICD classification systems.Results. We found no evidence for a “pure” pain syndrome according to the DSM- and ICD systems. On the contrary, we found highly significant evidence of a mixed psychosomatic condition.Conclusion. The results suggest a broad somatoform classification, with subgroups based on personality characteristics taking a stress—coping model into account, including interpersonal attachment behaviour. An alternative model of a diagnostic approach is presented.     

Psychometric evaluation and normative data of the Swedish version of the 10‐item perceived stress scale

The perceived stress scale (PSS) has been translated to several languages and validated in many cultures. The longer 14‐item version (PSS‐14), has been translated to Swedish and validated for Swedish use. However, the Swedish version of the shorter 10‐item version (PSS‐10) has not been validated before. Therefore, the aim of this study was to evaluate the Swedish version of the PSS‐10 with regard to reliability and validity, and to provide normative data. Data from 3,406 individuals who took part in the Västerbotten Environmental Health Study in Sweden were used. The respondents constitute a random sample, aged 18 to 79 years, and stratified for age and sex. They responded to the Swedish version of the PSS‐10 as well as to the hospital anxiety and depression scale, and the Shirom Melamed burnout questionnaire for assessment of construct validity. The results show that the PSS‐10 provides approximately normally distributed data, has good internal reliability (Cronbach's alpha 0.84), and has good construct validity with anxiety (r = 0.68), depression (r = 0.57), and mental/physical exhaustion (r = 0.71). The favorable psychometric properties of the Swedish version of the PSS‐10 suggest use of the instrument for assessing perceived stress in Swedish and similar populations.     

PTEN、p53和BAG-1在三阴乳腺癌中的表达及意义

为了研究PTEN、p53和BAG-1在三阴乳腺癌中的表达情况及临床病理意义,并讨论三者之间的关系.采用免疫组织化学SP法检测89例三阴乳腺癌中PTEN、p53、BAG-1的表达,其阳性表达率分别为44.9％、47.2％、73.0％,三者的表达均与患者的病理组织学分级、淋巴结转移情况有关（P＜0.05）.PTEN的表达与p53、BAG-1表达呈负相关;BAG-1与p53的表达呈正相关,提示三者在三阴乳腺癌中的表达存在一定关联性,临床上联合检测三者可能为TNBC预后评估、患者的个体化治疗提供一定的参考.     

Revisiting the factor structure of the 12-item Disgust Propensity and Sensitivity Scale – Revised: Evidence for a third component

The 12-item Disgust Propensity and Sensitivity Scale – Revised (DPSS-12) is widely used to assess the tendency for an individual to respond with disgust (i.e., disgust propensity) and how bothered an individual is by the experience of disgust (i.e., disgust sensitivity). However, heterogeneous items included in the DPSS-12 call into question the adequacy of its two-factor structure. The current study examined the factor structure of the DPSS-12 using two large, nonclinical student samples. Exploratory factor analyses revealed three lower order factors: (1) disgust propensity, (2) disgust sensitivity, and (3) self-focused/ruminative disgust. Confirmatory factor analyses supported the three-factor solution and demonstrated that the model fit better than a unidimensional or two-factor model. Further, a modified two-factor model that excluded the third factor provided a better fit than the original two-factor model. Additionally, the third domain explained a significant portion of the total variance, and evidenced a distinctive pattern of association with relevant constructs including obsessional symptoms. These data suggest the need to refine our knowledge about the latent structure of disgust reflected by this measure.     

The association between perceptions of daily experiences and self- and spouse-rated mood

A recent study by L. P. Rehm (Journal of Consulting and Clinical Psychology, 1978, 46, 854–859) reported strong associations between the daily report of pleasant and unpleasant events and a global mood rating. This study examined desirable and undesirable events in an effort to replicate and extend Rehm's work by having 26 married couples complete a daily event and mood checklist about husbands for 14 consecutive days. The group averaging strategy generally used to describe event-mood correlations was compared to a tabulation of significant individual correlations. The observed correlations were consistent with a previous study of pleasant events by P. M. Lewinsohn and M. Graf (Journal of Consulting and Clinical Psychology, 1973, 41, 261–268) and a study of unpleasant events by P. M. Lewinsohn and J. Talkington (Applied Psychological Measurement, 1979, 3, 83–101), yet were considerably smaller than those reported by Rehm. Wives' ratings of their husbands' mood revealed the same relationship with experiences as did husbands' self-rated mood. Differences in the populations studied and the event and mood assessments between our study and Rehm's could account for this finding. A tabulation approach to the data showed that few subjects actually achieved statistically significant associations in contrast to the group approach which indicated small associations across all subjects.     

The influence of mood on perceptions of social interactions

Interpreting our own and others' social behaviors is an important cognitive task in everyday life. Recent work in cognitive psychology suggests that temporary mood states may have a significant effect on the way information about common social events is processed. This study investigated how (a) a person's current mood, (b) the target of the judgments (self vs other), and (c) the characteristics of the social episode (formal-informal; intimate-nonintimate) influenced people's assessment of, and memory for, social behaviors. Subjects were videotaped while engaging in four different kinds of interactions with trained confederates. One day later subjects were hypnotized, and a happy, positive, or depressed, negative mood was induced. They then watched and rated their own and their partner's interactions on the videotape. Results showed strong mood influence on behavior assessments and recall memory, and significant effects due to target (self vs other) and the type of interaction episode. These results are discussed in terms of their implications for contemporary research on social cognition, and their relevance to cognitively based theories of social maladjustment and depression are considered.     

The eyes have it: Young children's discrimination of age in masked and unmasked facial photographs

The ability of preschool children to discriminate age, and their use of information from different facial areas in this task, was investigated. Most 4-year-olds were able to rank sets of seven facial photographs into age order successfully. Subsequently, they were presented with facial stimuli in which different regions of the face were masked out. Masking of the eyes produced a marked performance decrement, and masking of the nose and cheeks a slight decrement, relative to masking of either the mouth and chin, or of the hair and neck. Possible explanations of the results are discussed, together with the verbal comments of the children on the cues they were aware of using.     

Visual tracking in young infants: Evidence for object identity or object permanence?

Previous research has shown that 5-month-old infants visually anticipate a moving object's appearance after it disappears behind a screen. This experiment assesses the underlying basis for such anticipatory tracking. Three tracking tasks were presented to 5- and 9-month-old infants. In the Permanence task, the object's continuous existence was apparently violated while it was behind a screen. In the Feature and Trajectory tasks, the object's features or trajectory changed while behind the screen. Disruptions in the infant's smooth visual pursuit of the object were recorded. Five-mont-olds showed disruptions of visual tracking in the Feature and Trajectory tasks, but not in the Permanence task. The tracking of the 9-month-olds was disrupted in all three tasks. We conclude that both 5- and 9-month-olds possess rules specifying the identity of a moving object which is occluded. For 5-month-olds these rules are based upon the object's features and trajectory, but not upon a concept of object permanence. For 9-month-olds all three rules—feature, trajectory, and permanence—are utilized in visual tracking.
