Dishabituation in Aplysia can involve either reversal of habituation or superimposed sensitization

Dishabituation has been thought to be due either to reversal of the process of habituation or to a second process equivalent to sensitization superimposed on habituation. One way to address this question is by testing whether dishabituation and sensitization can be dissociated. Previous studies using this approach in Aplysia have come to different conclusions about the nature of dishabituation, perhaps because those studies differed in many respects, including (1) whether they also observed transient behavioral inhibition, and (2) whether they used test stimuli that activated the LE siphon sensory neurons or as yet unidentified sensory neurons. To attempt to resolve the apparent contradictions between the previous studies, we have explored the importance of these two factors by performing a parametric study of dishabituation and sensitization of gill withdrawal in a simplified preparation that does not exhibit transient behavioral inhibition, using two different test stimuli that are known to activate the LE (Touch) or unidentified (Not Touch) sensory neurons. We find that dishabituation and sensitization in this preparation have similar time courses and generally similar functions of shock intensity. However, under one condition, with the Not Touch stimulus 2.5 min after the shock, dishabituation has a reverse effect of shock intensity. Additional analyses suggest that dishabituation with the Not Touch stimulus 2.5 min after the shock is due to reversal of habituation, whereas 12.5 min after the shock, dishabituation is due to superimposed sensitization. These results thus suggest that dishabituation may involve either process in the same preparation, and begin to define the conditions that favor one or the other.     

Jung, the trickster writer, or what literary research can do for the clinician

This paper aims to show how literary scholarship can contribute to clinical debates by offering different methods of reading and interpreting works by Jung. Firstly, as texts form much of the means by which Jungian ideas are transmitted and worked upon, literary research offers methods of examining the way we read for authority and orthodoxy. Secondly, it is invaluable to look at the way in which Jung actually wrote. Jung portrays a dynamic psyche in action in his writings. His works are not only about a creative archetypal psyche, they enact and perform this creativity in the way in which he uses words. The rich playfulness demonstrated in The Collected Works is an example of a writer as a mythmaker of the psyche, one who absorbs unconscious creative energies into his writing in ways that dissolve modernity's cultural boundaries of science and art. In addition, the aesthetic component in Jung's writing is not a decoration of his ideas. Rather, his 'literary' qualities are themselves forms of argument about the fragile state of modern subjectivity. Using his essays on 'Synchronicity', and the 'Trickster', the paper will show these works to be responses to three related crises that still face clinicians and scholars today: the problematic role of the hero myth as an individuation narrative, the nature of 'science', and the crisis of western modernity itself in desperate need of psychic healing. The paper will show that where writing on synchronicity aims to individuate science by adding a 'feminine' Eros to its Logos biases, the Trickster essay is designed to ameliorate modernity by providing frameworks to make visible marginal or excluded material. In these works Jung tries to rejuvenate the modern world by re-connecting traditional symbolic systems with the psyche through myth as a language of psychic relating.     

Taste-aroma interactions in a ternary system: a model of fruitiness perception in sucrose/acid solutions

Cross-modal interactions between aroma, sweetness, and acidity were studied. A series of samples was presented to trained panelists who assessed strawberry flavor intensity using magnitude estimation with a reference modulus. The delivery of aroma stimuli from the different solutions was measured by monitoring exhaled breath using atmospheric pressure chemical ionization-mass spectrometry to determine whether there were any physicochemical effects on volatile release; no significant differences were noted. Three-dimensional predictive models were built to describe perceived strawberry flavor intensity as a function of concentrations of sucrose, acid, and volatiles. Analysis of the data identified two groups of panelists with different responses: For Group 1, increasing sucrose and/or acid levels also increased the perceived flavor intensity. For Group 2, changing sucrose concentrations had little effect, but increasing acid and/or volatile levels did. The results show different effects of organic and inorganic acids on perception, as well as clear interactions between the modalities of taste (sugar and acid) and aroma. The clustering of panelists' responses suggests that this phenomenon may depend on prior associations between the fruity flavor and the tastants.     

Relation of interest and self-efficacy occupational congruence and career choice certainty

A sample of 2145 adults completed the Personal Globe Inventory (PGI) as well as indicating their occupational choice and the certainty of this choice. The PGI yielded interest and self-efficacy scores and these were used with the occupational choice to calculate a congruence score for interests and one for efficacy. The prediction of career certainty by each congruence measure and their interaction was examined using hierarchical regression. The results indicated that while both interest and efficacy congruence were related to career certainty, efficacy congruence did not add to prediction above that obtained using interests congruence alone, however there was a substantial interaction. The agreement of interest congruence and efficacy congruence was related to a strong positive relation between congruence and certainty; whereas low agreement between interest and efficacy congruence was related to a non-significant relation between congruence and certainty. The results demonstrate the need to focus on both interest and efficacy and their agreement in our assessments and interventions.     

Countertransference as a prototype: The development of a measure

Countertransference is a concept that is widely acknowledged, but there exists little definitional consensus, making research in the area difficult. The authors adopted a prototype theory (E. H. Rosch, 1973a, 1973b; see C. B. Mervis & E. Rosch, 1981, for a review) to examine this construct because it conceptually fits well with constructs that elude explicit definition. In Study 1, 45 experienced psychologists highly agreed with the prototypicality of 104 different examples of countertransference providing support for the presence of a prototype. In Study 2, the usage of this prototype in a sample of 35 trainees was related to ability to perceive countertransference in a case example drawn from the literature and positively correlated with self-reports of their experiences of countertransference but not with their self-reported ability to manage countertransference once it was manifest. Implications for training and research are discussed.     

Duchenne display responses towards sixteen enjoyable emotions: Individual differences between no and fear of being laughed at

The present study aims to identify whether individuals’ with a fear of being laughed at (gelotophobia), respond with less facially displayed joy (Duchenne display) generally towards enjoyable emotions or only those eliciting laughter. Forty participants (no vs. gelotophobia) described their feelings to scenarios prototypical for the 16 enjoyable emotions proposed by Ekman (Emotions revealed: recognizing faces and feelings to improve communication and emotional life. Times Books, New York, 2003), while being unobtrusively filmed. Facial responses were coded using the Facial Action Coding System (FACS, Ekman et al. in Facial Action Coding System: a technique for the measurement of facial movement. Consulting Psychologists Press, Palo Alto, 2002). The gelotophobes showed less facial expression of joy compared to the non-gelotophobes (Hypothesis 1) and this effect was stronger for frequency and intensity of Duchenne displays towards laughter-eliciting enjoyable emotions than for no laughter-eliciting enjoyable emotions (Hypothesis 2). Moreover, the no gelotophobia group responded more strongly to laughter-eliciting than to no laughter-eliciting enjoyable emotions. Individuals with marked gelotophobia showed the reverse pattern, displaying less joy in laughter-eliciting emotions which may impact on their social interaction, as communication may break down when positive emotion are not reciprocated.     

Structure of interest in a Caribbean sample: Application of the Personal Globe Inventory

The structural validity of the Personal Globe Inventory (PGI, Tracey, 2002) as applied to a Caribbean sample of university students in Jamaica (N = 103) and Trinidad (N = 118) was examined. The fit of the data to Holland's six-type RIASEC, the PGI eight-type model, and the PGI spherical structure was examined using the randomized test of hypothesized order relations. The results demonstrated that the circular structure (i.e. RIASEC and the eight-type model), unlike the spherical structure, fits the Caribbean data well. No structural differences were found between gender and nationality. Further examination of the cultural perception of prestige in a Caribbean sample is warranted. Overall, the results support the structural validity of the PGI in Caribbean applications.     

Institutional Barriers to Participation in Adult Education Among African Americans within Religious Institutions

Numerous studies have identified deterrents to participation in adult education among adult learners, mainly in formal settings. The purpose of this study was to examine institutional deterrents to participation as identified among African Americans who are members of religious institutions, specifically African American Christian churches. Institutional deterrents were classified into six different rubrics. Results from the study suggest African American Christian churches should closely examine their policies and procedures for developing and marketing their educational programs and developing or enhancing teacher preparation techniques.     

Empathy,Vulnerability and Anxiety

ABSTRACT

A concept of empathy as openness to the emotional perspective of another is developed in opposition to a concept of sympathy as agreement with the emotional perspective of another. Empathy involves knowledge of how things are emotionally for the other person, which is not the same thing as knowledge of the other person’s emotions. Being open to another perspective requires the capacity to hold two perspectives in mind simultaneously – one that is one’s own perspective and at the same time the adopted perspective. This is why empathy can be so challenging for someone suffering from some kinds of anxiety.
