The hippocampus facilitates integration within a symbolic field

This paper attempts to elaborate a fundamental brain mechanism involved in the creation and maintenance of symbolic fields of thought. It will integrate theories of psychic spaces as explored by Donald Winnicott and Wilfred Bion with the neuroscientific examinations of those with bilateral hippocampal injury to show how evidence from both disciplines sheds important light on this aspect of mind. Possibly originating as a way of maintaining an oriented, first person psychic map, this capacity allows individuals a dynamic narrative access to a realm of layered elements and their connections. If the proposed hypothesis is correct, the hippocampus facilitates the integration of this symbolic field of mind, where narrative forms of thinking, creativity, memory, and dreaming are intertwined. Without the hippocampus, there is an inability to engage many typical forms of thought itself. Also, noting the ways these individuals are not impaired supports theories about other faculties of mind, providing insight into their possible roles within human thought. The evidence of different systems working in conjunction with the symbolic field provides tantalizing clues about these fundamental mechanisms of brain and mind that are normally seamlessly integrated, and hints at future areas of clinical and laboratory research, both within neuroscience and psychoanalysis.     

The Influence of Child-Directed Speech on Word Learning and Comprehension

This paper describes an investigation into the function of child-directed speech (CDS) across development. In the first experiment, 10–21-month-olds were presented with familiar words in CDS and trained on novel words in CDS or adult-directed speech (ADS). All children preferred the matching display for familiar words. However, only older toddlers in the CDS condition preferred the matching display for novel words. In Experiment 2, children 3–6 years of age were presented with a sentence comprehension task in CDS or ADS. Older children performed better overall than younger children with 5- and 6-year-olds performing above chance regardless of speech condition, while 3- and 4-year-olds only performed above chance when the sentences were presented in CDS. These findings provide support for the theory that CDS is most effective at the beginning of acquisition for particular constructions (e.g. vocabulary acquisition, syntactic comprehension) rather than at a particular age or for a particular task.     

The DSM‐IV‐TR and Culture: Considerations for Counselors

Although counselors receive training in both diagnosis and cultural foundations of human behavior, little literature or research integrates these 2 areas in order to facilitate culturally sensitive diagnostic practices. The authors attempt to rectify that lack by providing a review of the literature on the controversies associated with traditional diagnosis of cultural groups that differ from the dominant culture. Practical guidelines for culturally sensitive diagnosis are provided.     

Consciousness and modality: on the possible preserved visual consciousness in blindsight subjects

In a recent paper, Brogaard (2011) presents counter-arguments to the conclusions of an experiment with blindsight subject GR. She argues that contrary to the apparent findings that GR’s preserved visual abilities relate to degraded visual experiences, she is in fact fully unconscious of the stimuli she correctly identifies. In this paper, we present arguments and evidence why Brogaard’s argument does not succeed in its purpose. We suggest that not only is relevant empirical evidence in opposition to Brogaard’s argument, her argument misconstrues necessary criteria to decide whether a conscious experience is visual or not visual.     

Trying and the Arguments from Total Failure

New Volitionalism is a name for certain widespread conception of the nature of intentional action. Some of the standard arguments for New Volitionalism, the so-called arguments from total failure, have even acquired the status of basic assumptions for many other kinds of philosophers. It is therefore of singular interest to investigate some of the most important arguments from total failure. This is what I propose to do in this paper. My aim is not be to demonstrate that these arguments are inconsistent or that total failure and naked tryings are metaphysically impossible. Rather, my aim is be to build a case against the possibility of naked, independently existing tryings, by questioning how well we understand the scenarios invoked in their favour. Thus, rather than attempting to present a definitive metaphysical refutation of New Volitionalism, I attempt to diminish or demolish its underlying motivation.

Reconstructing N: A New Approach to Measuring Emotional Sensitivity

Neuroticism (N) assesses emotional sensitivity or lability, but the construct is poorly defined and instruments used to assess N are marred by a number of psychometric shortcomings. Neuroticism is also described in an overtly pejorative way, with items keyed for themes reflecting low self-esteem, anxiety, and depression. The present paper presents a revised model based on a new questionnaire entitled the Emotional Sensitivity Scale (ESS). Using an innovative scenario technique to generate items, exploratory factor analysis of the responses of 242 participants yielded orthogonal dimensions for positive (other-oriented) and negative (self-centered) emotional sensitivity, and the structure was confirmed using confirmatory factor analysis. Validation studies showed that the ESS dimensions were related in systematic ways to related psychometric instruments and that, as predicted, participants scoring high on the positive dimension were better able to recognize displayed emotions. The new scale offers a basis for extending the research on emotional sensitivity using empirically discriminable positive and negative components.     

Suppression of mouse killing and apomorphine-induced social aggression in rats by local anesthesia of the mystacial vibrissae.

Local anesthesia of the facial epidermis can effect a substantial decrease in shock-elicited fighting of paired rats. The present experiments constitute methodological extensions to mouse killing and spontaneous drug-induced social aggression. In the first experiment, known mouse-killing rats were given bilateral lidocaine or placebo injections administered under ether anesthesia. Attack and kill latencies were significantly longer under lidocaine than under placebo; all subjects killed under placebo, whereas a third of all subjects failed to kill on the initial lidocaine test. On subsequent lidocaine testing, latencies decreased and nonkilling rats killed. In a second experiment intense apomorphine-induced conspecific fighting of rats preselected for aggressiveness was markedly reduced following lidocaine anesthesia. The comparative results of both experiments are interpreted in reference to theoretical assertions regarding the import of sensory information in stimulus-bound attack and the typology of central aggression systems.     

Form of redundancy as a determinant of tachistoscopic word recognition

Single letters and redundant CVCs and CCCs were presented at threshold durations and followed by a pattern mask. Performance on three-letter stimuli was greater than on single letters. The increased performance was consistent with a state model of perceptual independence. Conditional redundancy increased the frequency with which all three letters were accurately reported as compared to correlational redundancy. Meaning and pronounceability had little effect on performance.
