Pavlovian eyeblink conditioning in combat veterans with and without post-traumatic stress disorder

Several recent studies have investigated relationships between post-traumatic stress disorder (PTSD) and learning and memory problems. These reports have found in general that not only does PTSD affect trauma-related memories, but when patients with PTSD are compared with similar trauma patients without PTSD, general memory impairments have been found. The present paper reports a study in which associative learning, using Pavlovian eyeblink conditioning, was investigated in combat veterans with and without chronic PTSD, using interstimulus intervals of 500 and 1000 msec in two separate experiments. Although several recent reports suggest that larger-magnitude autonomic conditioned responses occur in patients with PTSD during Pavlovian conditoning, the present study found evidence of impaired Pavlovian eyeblink conditioning in combat veterans with and without PTSD, compared to non-combat veterans. Although these data suggest that combat leads to an impaired associative learning process regardless of whether PTSD is apparent, a group of community-dwelling combat veterans not under medical treatment showed normal conditioning, suggesting that variables other than prior combat must also be involved.     

The interpersonal and Freudian traditions: convergences and divergences

The traditional Freudian and interpersonal schools of psychoanalysis diverged during the psychoanalytic wars in New York in the 1940s. Each has developed from a different set of assumptions concerning the mind, especially the role of structure and the role of interaction. Recent developments in both schools in the last twenty years suggest a convergence and overlap in theory and technique. The relevant history of the divergence is examined and the work of three contemporary interpersonal writers explored in depth. That work is contrasted with contemporary developments in traditional Freudian psychoanalysis.     

Subjectivity and Orientation in Levinas and Kant

Continental Philosophy Review - This essay presents an argument for reconceptualizing subjectivity as orientational rather than foundational in nature. My focus is on the work of Emmanuel Levinas...     

Familiarity and pronounceability of nouns and names

Ratings of familiarity and pronounceability were obtained from a random sample of 199 surnames (selected from over 80,000 entries in the Purdue University phone book) and 199 nouns (from the Ku?era-Francis, 1967, word database). The distributions of ratings for nouns versus names are substantially different: Nouns were rated as more familiar and easier to pronounce than surnames. Frequency and familiarity were more closely related in the proper name pool than the word pool, although both correlations were modest. Ratings of familiarity and pronounceability were highly related for both groups. A production experiment showed that rated pronounceability was highly related to the time taken to produce a name. These data confirm the common belief that there are differences in the statistical and distributional properties of words as compared to proper names. The value of using frequency and the ratings of familiarity and pronounceability for predicting variations in actual pronunciations of words and names are discussed.     

Representation of facial expressions of emotion

Inversion interferes with the encoding of configural and holistic information more than it does with the encoding of explicitly represented and isolated parts. Accordingly, if facial expressions are explicitly represented in the face representation, their recognition should not be greatly affected by face orientation. In the present experiment, response times to detect a difference in hair color in line-drawn faces were unaffected by face orientation, but response times to detect the presence of brows and mouth were longer with inverted than with upright faces, independent of the emergent expression (neutral, happy, sad, and angry). Expressions are not explicitly represented; rather, they and the face configuration are represented as undecomposed wholes.     

The Role of Self-Awareness and Self-Monitoring in Charismatic Relationships

In this paper, a hypothesis from a theory of charismatic relationships is examined that incorporates follower's level of self-monitoring and state of self-awareness. It is argued that changes in the state of self-awareness affect the characteristics of the short-term charismatic relationship between leader and follower, but only for high self-monitoring followers. Providing support for the hypothesis was a repeated-measures study. Participants ( N = 78) viewed video vignettes of charismatic leaders presenting different messages, in either a high or low self-awareness condition. When high in self-awareness, participants with a high self-monitoring orientation were more likely than when in a state of low self-awareness to internalize only those messages congruent with their values and beliefs.     

Gangsta’ Rap and a Murder in Bakersfield1

The present study explores the biasing effects of gangsta’ rap lyrics on subject perceptions of a murder trial defendant's personality. The lyrics were those actually authored by a defendant in a murder trial on which the present author was a psychological consultant for the defense. Results strongly indicate that the defendant was seen as more likely to have committed a murder than had he not been presented as authoring such lyrics. Surprisingly, results also show that the writing of such rap lyrics was more damning in terms of adjudged personality characteristics than was the fact of being charged with murder.
