Validation of affective and neutral sentence content for prosodic testing

Conducting a study of emotional prosody often requires that one have a valid set of stimuli for assessing perceived emotion in vocal intonation. In this study, we created a list of sentences with both affective and neutral content, and then validated them against rater opinion. Participants read sentences with content that implied happiness, sadness, anger, fear, or neutrality and rated how well they could imagine each sentence being expressed in each emotion. Coefficients of variation and intraclass correlations were calculated to narrow the list to affective sentences that had high agreement and neutral sentences that had low agreement. We found that raters could easily identify most emotional content and did not ascribe any unique emotion to most neutral content. We also found differences between the intensity of male and female ratings. The final list of sentences is available on the Internet (www.med.upenn.edu/bbl/) and can be recorded for use as stimuli for prosodic studies.     

Attachment Style and Family Functioning as Discriminating Factors in Eating Disorders

This study sought to examine the extent to which family environment and attachment styles are concurrently related to eating disorders. The Adult Attachment Scale and the Family Environment Scale were administered to 25 anorexic and 33 bulimic female patients at intake in an eating disorder clinic, and 37 age-matched female controls. Eating disorder patients were found to be less secure, more avoidant, and more anxious than controls. The families of eating disorder patients were found to be less cohesive, expressive, and encouraging of personal growth than were controls. Low encouragement of personal growth and uncertain attachment styles may be manifestations of family difficulties in supporting the child during the process of separation individuation, and exploration of the outside world.     

Visual imagery and the discrimination of differences between altered pictures simultaneously and successively presented.

Ten 'good' visual imagers and ten 'poor' imagers, representing the upper and lower halves of an unselected sample of adult volunteers, were given a task of detecting differences between altered pictures presented in pairs, either simultaneously or successively. Performance was measured by reaction time. 'Good' imagers reacted faster than 'poor' imagers, and the mode of presentation (simultaneous v. successive) did not affect their performances. 'Poor' imagers, on the other hand, reacted significantly slower when the pictures compared were presented successively. The results suggest that self-rated visual imagery can be used to predict the successful recall of visual information required in a discrimination task.     

Identification of partially presented meaningless patterns: effect of completeness and distinctiveness

The role of parts versus that of wholes in a visual perception has been debated for a century as two opposite approaches, namely, an analytic and holistic. In two psychophysical experiments we investigated whether the stimulus completeness or distinctiveness is essential for identification of the partially presented patterns under brief presentation conditions. For this purpose, a special class of stimuli was constructed in such a way that the patterns could be divided into informative and redundant parts. The first experiment clearly demonstrated the importance of the redundant part for effective pattern identification for the majority of subjects. The second experiment revealed the direct dependence of identification accuracy of the patterns on their completeness (2, 3, 4, 5, or 6 elements). Familiarisation of subjects with the test stimuli influenced the strength of this dependence.     

Brief cognitive-behavioral phone-based intervention targeting anxiety about the threat of attack: a pilot study

A brief, cognitive-behavioral, phone-based intervention was employed with an Israeli sample experiencing anticipatory anxiety about potential war-related attacks. In this quasi-experimental controlled pilot study, the cognitive-behavioral therapy intervention (diaphragmatic breathing and a modified cognitive-restructuring technique) was compared with the standard hotline care administered when worried citizens called a mental health emergency hotline in Israel. Individuals (n=32) were administered anxiety and worry measures pre-intervention, post-intervention, and three days post-intervention. The results indicated that anxiety levels decreased for the experimental and control group immediately post-intervention; however, three days later, the levels of anxiety in the CBT group continued to decline, while anxiety levels in the control group reached pre-intervention levels on two of the three outcome measures. These results suggest that CBT can be effectively delivered by paraprofessionals over the phone, which is cost-effective and efficient. Limitations are considered, and implications for treating individuals coping with the threat of terrorism are discussed.     

The Challenge of the Concealed Knowledge Polygraph Test

This paper introduces the concealed knowledge polygraph test (CKT) and suggests that it might be useful for the criminal justice system. The main point is that the CKT is a standard and objective psychological test that can to some extent protect the innocent from false allegation. A review of 15 mock crime studies of the CKT supports this contention. It revealed average detection rates of 80.6% for guilty examinees and 95.9% for the innocent. Furthermore, in 11 of these studies no false positive identifications (i.e. failures to exonerate innocent suspects) were observed. Two field studies revealed similar results, with false-positive error rates that are not larger than expected by chance. However, in the field studies, the detection rates for guilty suspects were substantially lower than those obtained in the 15 experimental studies. Suggestions for enhancing the detection rate of guilty suspects in real life settings are provided.Finally, the effects of several possible countermeasures, such as the use of drugs, biofeedback training and behavioural countermeasure maneouvres, are discussed. It seems that drugs and biofeedback are not effective in the CKT. However, at least the electrodermal measure is vulnerable to the effects of behavioural countermeasures. Possible ways to deal with the problem are discussed.     

Voice recognition and the ontological status of self-deception

Douglas and Gibbins (1983) recently argued that our demonstration that errors in self-other recognition are often instances of self-deception was inadequate. In their study, they found that both self-other and acquaintance-other recognition errors met two of the four criteria we had offered as necessary and sufficient for ascribing self-deception. They presented no evidence that either type of recognition error was not an instance of self-deception. Here we describe the original basis of our demonstration and point out the logical fallacy in Douglas and Gibbins' argument.     

Performing and Declining PGD: Accounts of Jewish Israeli Women Who Carry a <Emphasis Type="Italic">BRCA1/2</Emphasis> Mutation or Partners of Male Mutation Carriers

To describe factors associated with preimplantation genetic diagnosis (PGD) decisions among Jewish Israeli BRCA1/2 carriers or spouses of a male carrier, we contacted all women who initiated PGD consultation for embryonic BRCA1/2 mutation detection at Sheba Medical Center, prior to March 2014. Applying a qualitative approach, we asked women to elaborate on the factors they considered in either opting for PGD or discontinuing the screening procedure. Participants were 18 Jewish Israeli women; 14 were carriers of one of the Ashkenazi founder mutations in BRCA1/2, and four were spouses of male mutation carriers, who underwent at least one cycle of PGD. Prior to seeking PGD, ten of the women had no children. At the time of the interview, all but three had at least one child. Three factors emerged as key motivators for PGD: having witnessed the disease in a close relative (n = 12); prior IVF treatment for infertility (n = 12); and having pre-existing frozen embryos (n = 6). Ten women withdrew from the PGD process due to clinical, logistical, and financial reasons. In conclusion, most women decided to withdraw from PGD instead of continuing until a successful conception was achieved. Those who opted for PGD attributed their discontinuation of further screening to the emotional burden that is greatly intensified by practical difficulties.     

The relationship between history of violent and criminal behavior and recognition of facial expression of emotions in men with schizophrenia and schizoaffective disorder

Social psychological research underscores the relation between aggression and emotion. Specifically, regulating negative affect requires the ability to appraise restraint‐producing cues, such as facial signs of anger, fear and other emotions. Individuals diagnosed with major mental disorders are more likely to have engaged in violent behavior than mentally healthy members of the same communities. We examined whether violent and criminal behavior in men with schizophrenia is related to emotion recognition abilities. Forty‐one men with schizophrenia underwent a computerized emotion discrimination test presenting mild and extreme intensities of happy, sad, angry, fearful and neutral faces, balanced for gender and ethnicity. History of violence was assessed by the Life History of Aggression Scale and official records of arrests. Psychopathology was rated using the Positive and Negative Symptom Scale. Criminal behavior was associated with poor emotion recognition, especially for fearful and angry facial expressions. History of aggression was also associated with more severe positive symptoms and less severe negative symptoms. These findings suggest that misinterpretation of social cues such as angry and fearful expression may lead to a failure in socialization and adaptive behavior in response to emotional situation, which may result in a higher number of criminal arrests.
