Relational Trouble: Reply to Commentaries

This reply to the commentaries by Corbett, Hansell, and Stern explores whether Lacan's concept of the real can—or should—be translated into more readily recognizable terms. It extends our previous discussion of impossibility by arguing that not all ideas and experiences can be brought within the realm of the known and familiar. We suggest that impossibilities of meaning should not be understood primarily in phenomenological terms, and we demur from the assessment that our concept of impossibility offers nothing for clinical work. Claiming that what resists meaning also impedes relationality, we encourage relational theorists to address the nonrelational processes that subtend relationality, including the relation between analyst and patient. We acknowledge that the theory of impossibility—or what we now call “negative mediation”—raises a fundamental challenge to relational theory, but we insist that disruptions of relationality need not be considered pathological. Taking into account the nonrelational may enhance rather than impoverish relational psychoanalysis.     

Relationships among Dispositional Attributional Style,Trauma-Specific Attributions,and PTSD Symptoms

The learned helplessness model and its various revisions suggest that causal attributions influence responses to events. This study examined relationships among the 3-factor symptom clusters of posttraumatic stress disorder (PTSD) represented in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM–IV; American Psychiatric Association, 1994) and the individual dimensions of dispositional attributional style and trauma-specific attributions (i.e., internal–external, stable–unstable, global–specific). Relationships among attributions and clusters of PTSD symptoms represented by the 4-factor dysphoria model were also examined. Trauma-specific attributions were most predictive of PTSD symptoms, with higher associations for avoidance and numbing symptoms compared to arousal symptoms in the three-factor model and higher associations for dysphoria symptoms compared to arousal and avoidance symptoms in the four-factor dysphoria model. Results suggest that cognitive vulnerabilities could underlie the comorbidity between PTSD and depression and might represent a high-impact target for treatment.     

A Method to Optimize the Response Range While Maintaining Rorschach Comprehensive System Validity

Brief and lengthy Rorschach records have been identified as common problems in protocol administration. Clinicians have debated how to prevent overly short and long records, but they have been reluctant to alter standardized administration for fear of introducing bias. The present study examines a nonintrusive method for constraining responses by prompting for an extra response when only one is offered per card and by removing the card after four responses are given. Among patients who typically produce brief records, consisting of a residential sample of civil and forensic patients with a range of disordered thinking, the alternative administration method demonstrated improved Comprehensive System validity in assessing thought disorder and eliminated the need to readminister the test due to fewer than 14 responses. The findings have clinical implications for protocol administration with thought-disordered populations that typically produce brief records.     

The Negative Shadow Cast by Positive Psychology: Contrasting Views and Implications of Humanistic and Positive Psychology on Resiliency

Resiliency is the ability to survive, or even thrive, during adversity. It is a key construct within both humanistic and positive psychology, but each sees it from a contrasting vantage. Positive psychology decontextualizes resilience by judging it as a virtue regardless of circumstance, while humanistic psychology tends to view it in a more holistic way in relationship to other virtues and environmental affordances, clarifying how resiliency can actually be either a virtue or a vice depending upon circumstances. Adolf Hitler is presented as an example of a resilient person who would not be seen as virtuous, and the US Army Comprehensive Soldier Fitness study training warfighters in resiliency illustrates possible ethical problems with a decontextualized view of resiliency.     

Heterogeneity in Verbal Memory: A Marker of Preclinical Alzheimer's Disease?

ABSTRACT

Demonstrations of memory changes in those at risk for Alzheimer's disease by the presence of the APOE e4 allele have been inconsistent to date. The present study went beyond traditional analyses of central tendency (i.e., group differences on mean test scores) and also conducted distribution analyses to search for subtle cognitive differences in subgroups of normal-functioning elderly persons with the APOE e4 genotype. The results of the study revealed that (a) the e4 and non-e4 groups failed to differ in terms of their mean scores on tests of memory and verbal skills; and (b) relative to the non-e4 group, the e4 subjects had significantly greater heterogeneity of variance on the memory measures but not on fundamental verbal skills. Logistic regression analyses indicated that the discrepancy in scores on the memory measures was a significant predictor of genotype group membership (82% correct classification rate). Implications of these findings for the detection of a preclinical phase of AD are discussed.     

Force and Timing Variability in Rhythmic Unimanual Tapping

In 3 experiments the interdependencies between timing and force production in unimanual paced and self-paced rhythmic tapping tasks were examined as participants (N = 6 in each experiment) tapped (a) to 1 of 3 target periods (333 ms, 500 ms, and 1,000 ms), while they simultaneously produced a constant peak force (PF) over a 50-s trial; (b) to produce 1 of 3 target forces (5, 10, and 15 N) at their preferred frequency, while keeping their rhythm as invariant as possible; and (c) to all combinations of target force and period. The results showed that (a) magnitudes of force and period were largely independent; (b) variability in timing increased proportionally with tapping period, and the variability in force increased with peak force; (c) force variability decreased at faster tapping rates; and (d) timing variability decreased with increasing force levels, (e) Analysis of tap-to-tap variability revealed adjustments over sequences of taps and an acceleration in the tapping rate in unpaced conditions. The interdependencies of force and time are discussed with respect to the challenges they provide for an oscillator-based account.     

Mechanisms of verbal memory impairment in four neurodevelopmental disorders

Profiles of verbal learning and memory performance were compared for typically developing children and for four developmental disorders characterized by different patterns of language functioning: specific language impairment, early focal brain damage, Williams Syndrome, and Down Syndrome. A list-learning task was used that allowed a detailed examination of the process of verbal learning, recall, and recognition (California Verbal Learning Test--Children's Version). Distinct patterns of performance characterized the four disorders. These patterns were consistent with the language deficits typically seen in the disorders, with the exception of a dissociation seen in Williams Syndrome.     

Prelinguistic evolution in early hominins: whence motherese?

In order to formulate hypotheses about the evolutionary underpinnings that preceded the first glimmerings of language, mother-infant gestural and vocal interactions are compared in chimpanzees and humans and used to model those of early hominins. These data, along with paleoanthropological evidence, suggest that prelinguistic vocal substrates for protolanguage that had prosodic features similar to contemporary motherese evolved as the trend for enlarging brains in late australopithecines/early Homo progressively increased the difficulty of parturition, thus causing a selective shift toward females that gave birth to relatively undeveloped neonates. It is hypothesized that hominin mothers adopted new foraging strategies that entailed maternal silencing, reassuring, and controlling of the behaviors of physically removed infants (i.e., that shared human babies' inability to cling to their mothers' bodies). As mothers increasingly used prosodic and gestural markings to encourage juveniles to behave and to follow, the meanings of certain utterances (words) became conventionalized. This hypothesis is based on the premises that hominin mothers that attended vigilantly to infants were strongly selected for, and that such mothers had genetically based potentials for consciously modifying vocalizations and gestures to control infants, both of which receive support from the literature.     

Semantic memory and verbal working memory correlates of N400 to subordinate homographs

N400 is an event-related brain potential that indexes operations in semantic memory conceptual space, whether elicited by language or some other representation (e.g., drawings). Language models typically propose three stages: lexical access or orthographic- and phonological-level analysis; lexical selection or word-level meaning and associate activation; and lexical integration, sentence- and discourse-level operations. The exact stage that N400 reflects is unknown, although opinion favors lexical integration over lexical selection. Surprisingly, little research has assessed relationships between neuropsychological measures of semantic memory fund of information or verbal working memory capacity and N400. Subjects performed a homograph disambiguation comprehension task with minimal working memory load. Short sentences read: The noun was adjective/verb. The nouns were either homographs or unambiguous. The adjective/verb was disambiguating for the homograph, and congruent or incongruent for the unambiguous noun. The primary noun of interest was the subordinate homograph. Comprehension of the subordinate meaning should correlate with semantic memory stores, reflecting greater knowledge. If N400 primarily reflects lexical access operations, it should also correlate with measures of semantic knowledge. If N400 reflects lexical integration, it should correlate with measures of working memory capacity. Comprehension errors were associated with semantic memory stores, but not working memory capacity. N400 was related to working memory capacity, but not semantic knowledge, suggesting that N400 primarily reflects late-stage working memory operations. N400 to subordinate disambiguating words was larger with greater working memory capacity, and thus may index the absolute capacity of working memory rather than difficulty in contextual integration.
