Content filtering human speech: A simple electronic system

The use of electronic bandpass filtering for content-masking speech samples in studies on expressive aspects of vocal behavior is discussed. A simple electronic filtering system, which can be built easily and which can be adopted readily for a variety of applications, is described.     

Vocal cues to deception: A comparative channel approach

The study investigated the leakage potential of different voice and speech cues using a cue isolation and masking design. Speech samples taken from an earlier experiment were used in which 15 female students of nursing dissimulated negative affect produced by an unpleasant movie or told the truth about positive affect following a pleasant movie. Several groups of judges rated these speech samples in five conditions: (1) forward or clear, (2) electronic filtering, (3) random splicing, (4) backwards, (5) pitch inversion, (6) tone-silence sequences. The results show that vocal cues do indeed carry leakage information and that, as reflected in the differences among the conditions masking different types of cues respectively, voice quality cues may be centrally implicated. In addition, gender differences in decoding ability are discussed.     

The short-term storage as a buffer memory between long-term storage and the motor system: A simultaneous-processing model

It is assumed that in a free-recall task the short-term store serves as a memory buffer between the long-term store and a final motor stage of word production. Because of this the retrieval process in long-term store is not hindered by the final motor stage of word production since continued output from the long-term store queues in the buffer for motoric processing. Otherwise a time consuming communication between the two processes would be necessary. A stochastic model of this conceptualization is provided to predict the temporal course of free recall as well as a paradigm in which the contribution of the short-term store in free recall can be studied. The experimental results from this paradigm were used to test the model and to estimate short-term storage capacity on the basis of the time course of free recall. The model predictions were in good agreement with the data and the capacity estimate coincides well with estimates found by totally different methods reported in the literature.     

Coping Mechanisms for Psychosomatic Symptoms among Aging Roman Catholic German priests

To identify and investigate coping mechanisms and other factors which may impact upon the psychosomatic symptoms of aging German Roman Catholic priests. A cross-sectional study was conducted among 499 aging German Roman Catholic priests with standardized questionnaires: Brief Symptom Inventory, Coping Inventory Stressful Situations, and Religious Coping Scale. Task-Oriented Coping exhibited a significant difference between the two groups. Multiple regression analyses indicated that psychosomatic symptoms could be best predicted by means of Task-Oriented Coping mechanisms, identification with priesthood, and by a low Negative Religious Coping. The success of adaptive coping processes for older clergy may depend on how they employ strategies, strengthen their spiritual dimensions, and manage important psychosocial aspects of aging. In our sample, Depression and Somatization are explained best by Emotion-Oriented Coping. It is desirable for aging priests to be aware of protective factors like Role Identification, Task-Oriented Coping, and low Negative Religious Coping, which may be helpful in improving their psychological well-being.     

Attending to emotional expressions: no evidence for automatic capture in the dot-probe task

Research on automatic attention to emotional faces offers mixed results. Therefore we examined validity effects for facial expressions of different emotions (compared to neutral faces) with a dot-probe paradigm in seven studies (total N?=?308). Systematic variations of type of emotion, CTI, task, cue size, and masking allow for a differentiated assessment of attentional capture by emotions and possible moderating factors. Results indicate a general absence of emotional validity effects as well as a lack of significant interactions with either of the manipulated factors, indicating that facial expressions of emotions do not capture attention in a fully automatic fashion. These findings suggest that situational and contextual factors have to be taken into account when investigating attentional capture of emotional faces.

Well-being in major depression and social phobia with and without comorbidity

Background/Objective: Lower levels in well-being have been observed in individuals with Major Depression (MDD) and Social Phobia (SP), but well-planned direct comparisons with control individuals, not suffering from a mental disorder, are lacking. Furthermore, MDD is highly comorbid with anxiety disorders, and SP with depressive disorders. This study is among the first to examine differences in well-being in individuals with a clinical diagnosis of MDD or SP compared to individuals with no such diagnosis and to test differences in well-being within the combined diagnostic categories respective with and without anxiety-depressive comorbidity. Method: Participants were 119 individuals with a diagnosis of MDD, 47 SP and 118 controls. Results: Results revealed that overall well-being as well as emotional, psychological, and social well-being were lower in the MDD and SP group compared to the control group. Individuals with comorbidity reported lower well-being than individuals without comorbidity. Conclusions: These findings have clinical implications as presence of comorbidity may require a different therapeutic approach than with no comorbidity.     

Vergleich zweier diagnostischer Ans?tze zur Erfassung der Sexualfantasien p?dophiler M?nner

Two diagnostic approaches to measure sexual fantasies, the Wilson Sexual Fantasy Questionnaire (WSFQ; Wilson 1988, Sex Marital Ther 3:45) as a quantitative self-report measure and the qualitative content analysis categories for the fantasy content, have been examined regarding their quality and capability for identifying pedophilic fantasies. For this purpose 33 men from the general community were selected and compared with 24 adult men from the project ??Kein Täter werden?? (avoid being a perpetrator) at the Institute of Sexology and Sexual Medicine, Charité Clinical Center, Berlin, all fulfilling diagnostic criteria of pedophilia according to DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision) (American Psychiatric Association 2000, Washington). The examination revealed that the reliability of the WSFQ scales (Cronbach??s ??) varied between moderate and good. The interrater reliability coefficients of content analysis categories ranged between moderate and predominantly good and very good. The WSFQ identified a generalized impersonal character only as a main feature of pedophilic fantasies and proved to have limited capability for identification of specific contents of sexual fantasies of persons with these diagnoses. In contrast, content analysis categories allowed identification of a set of specific features of the fantasized partners, pedophilic men and the sexual contacts in addition to the age and prepubertal body of a preferential partner which might be traced back to the preference for prepubertal age. Replication studies are necessary for evaluation of the current findings on the basis of a representative sample of men with pedophilia. These findings might be of primary use for the diagnosis of pedophilia.     

Effects of task-irrelevant texture motion on time-to-contact judgments

We investigated the effect of local texture motion on time-to-contact (TTC) estimation. In Experiment 1, observers estimated the TTC of a looming disk with a spiral texture pattern in a prediction-motion task. Rotation of the spiral texture in a direction causing illusory contraction resulted in a significant TTC overestimation, relative to a condition without texture rotation. This would be consistent with an intrusion of task-irrelevant local upon task-relevant global information. However, illusory expansion did not cause a relative TTC underestimation but rather also a tendency towards overestimation. In Experiment 2, a vertical cylinder moved on the frontoparallel plane. Observers judged its TTC with a finish line. The cylinder was textured with stripes oriented in parallel to its longitudinal axis. It was either not rotating, rotating such that the stripes moved towards the finish line (i.e., in the same direction as the contour), or rotating such that the stripes moved away from the finish line. Both types of texture motion caused TTC overestimation compared to the static condition. Experiment 3 showed that the different effects of task-relevant and task-irrelevant texture motion are not a mere procedural effect of the prediction-motion task. In conclusion, task-irrelevant local motion and global motion are neither averaged in a simple manner nor are they processed independently.
