The termination phase of combined therapy

Three different kinds of termination are described and discussed. In combined therapy the group can help to resolve and clarify the meanings of moves to terminate therapy. The role of the therapist's countertransferences in this stage of the work is important to consider, and here, too, the group is an important part of the work. The author sees termination as an important part of the treatment process. In combined therapy it may be more complex but it also allows for a fuller exploration of the relevant issues.     

The role of dichotic listening performance and tasks of executive functions in reading impairment: a discriminant function analysis.

This study focused on the role of dichotic listening performance for the identification of reading impaired subtypes. Dichotic listening (DL), using verbal stimuli, has shown to be a valid measure of language lateralization. Usually, lateralization is estimated from the proportion of right ear over left ear accuracy during a free recall test procedure. However, it has been suggested that a more accurate estimate of laterality can be obtained by using a directed attention procedure. A sample of 43 reading disabled children of whom 18 showed signs of impaired language comprehension skills and 25 without language comprehension impairments, were compared to 20 age, and gender, matched controls on dichotic listening performance in both an unbiased free recall task and in a directed attention task using consonant-vowel syllables as dichotic stimuli. A laterality index was calculated for left and right ear stimuli reported during both the free recall condition and the attended ear-scores for the two directed attention conditions. Although both DL procedures yielded significant group differences, with a lower laterality score for the reading disabled compared to the controls, there was no main effect of DL-procedure or group x procedure interaction. Taken alone, DL performance could correctly classify 42% of the reading impaired samples, but together with other measures of executive functions, discriminant function analyses yielded 90.74% accuracy in classifying reading impaired children. The result indicates that DL together with tests of executive functions are valuable tools for assessment of reading impaired subjects.     

Stimulus position functions in tachistoscopic identification tasks: Scanning,rehearsal, and order of report

Three experiments were conducted to investigate the locus of attentional control under the information-overload conditions stemming from tachistoscopic presentation of a horizontally arranged row of letters. In Experiment 1, left-right visual field accuracy differences were greater in a whole- than in a single-report task, reflecting a pronounced influence of report order bias effects. However, accuracy in the single-report task, which is relatively unaffected by report order biases, also declined from left to right across stimulus positions. In Experiment 2, single-report task requirements which provided an opportunity for rehearsal had negligible effects on the shape of the stimulus-position function. In Experiment 3, the leftright accuracy differences were observed to vary as a function of cue delay interval in a single-report visuospatial probe task. The degree of left-field superiority was negligible with a short delay interval, and much greater with longer delay intervals. The results are discussed in terms of a cognitive scanning operation.     

Aging, practice, and perceptual tasks: a diffusion model analysis

Practice effects were examined in a masked letter discrimination task and a masked brightness discrimination task for college-age and 60- to 75-year-old subjects. The diffusion model (Ratcliff, 1978) was fit to the response time and accuracy data and used to extract estimates of components of processing from the data. Relative to young subjects, the older subjects began the experiments with slower and less accurate performance; however, across sessions their accuracy improved because the quality of the information on which their decisions were based improved, and this, along with reduced decision criteria, led to shorter response times. For the brightness, but not the letter, discrimination task, the older subjects' performance matched that of the younger group by the end of 4 sessions, except that their nondecision components of processing were slightly slower. These analyses illustrate how a well-specified model can provide a unified view of multiple aspects of data that are often interpreted separately.     

The unity and diversity of executive functions and their contributions to complex "Frontal Lobe" tasks: a latent variable analysis

This individual differences study examined the separability of three often postulated executive functions-mental set shifting ("Shifting"), information updating and monitoring ("Updating"), and inhibition of prepotent responses ("Inhibition")-and their roles in complex "frontal lobe" or "executive" tasks. One hundred thirty-seven college students performed a set of relatively simple experimental tasks that are considered to predominantly tap each target executive function as well as a set of frequently used executive tasks: the Wisconsin Card Sorting Test (WCST), Tower of Hanoi (TOH), random number generation (RNG), operation span, and dual tasking. Confirmatory factor analysis indicated that the three target executive functions are moderately correlated with one another, but are clearly separable. Moreover, structural equation modeling suggested that the three functions contribute differentially to performance on complex executive tasks. Specifically, WCST performance was related most strongly to Shifting, TOH to Inhibition, RNG to Inhibition and Updating, and operation span to Updating. Dual task performance was not related to any of the three target functions. These results suggest that it is important to recognize both the unity and diversity of executive functions and that latent variable analysis is a useful approach to studying the organization and roles of executive functions.     

Coherent EEG indicators of cognitive binding during ambiguous figure tasks

We tested the hypothesis that perception of an alternative image in ambiguous figures would be manifest as high-frequency (gamma) components that become synchronized over multiple scalp sites as a "cognitive binding" process occurs. For 171 combinations of data from 19 electrodes, obtained from 17 subjects and 10 replicate stimuli, we calculated the difference in correlation between the response to first seeing an ambiguous figure and when the alternative percept for that figure became consciously realized (cognitively bound). Numerous statistically significant correlation differences occurred in all frequency bands tested with ambiguous-figure stimulation, but not in two kinds of control data (a reaction-time test to sound stimuli and a no-task, mind-wandering test). Statistically significant correlation changes were widespread, involving frontal, parietal, central, and occipital regions of both hemispheres. Correlation changes were evident at each of five frequency bands, ranging up to 62.5 Hz. Most of the statistically significant correlation changes were not between adjacent sites but between sites relatively distant, both ipsilateral and contralateral. Typically, these correlation changes occurred in more than one frequency band. These results suggest that cognitive binding is a distinct mental state that is reliably induced by ambiguous-figure perception tasks. Coherent oscillations at multiple frequencies may reflect the mechanism by which such binding occurs. Moreover, different coherent frequencies may mediate different components of the total cognitive-binding process.     

Dreaming of freud: Ferenczi,freud, and an analysis without end

The beginning of this paper documents Sigmund Freud's pre-psychoanalytic experience as a ‘first hand’ observer of childhood behavior both professionally and as the patriarch of a large extended family in Vienna. During 1898, Freud was in the midst of an intensive correspondence with Wilhelm Fliess – his most trusted confidant, mentor and colleague – when he wrote, in part, about his sister Marie whose family was relocating in Berlin. She was apparently about to consult Fliess as her prospective physician. During the process, Freud voiced psychological assessments not only about his sister; but, also about her husband and their three daughters. The youngest among them was a 5-year old whom he characterized as “a rather gifted child, severely [hysterical]” (bracketed word in quotation juxtaposed for clarity).

Eleven years later, Freud wrote a case study about a 5-year old boy whose pseudonym, for publication purposes, was Little Hans. The life of Little Hans (as well as the lives of his parents) has been thoroughly examined and we now know something about how he matured as an adult. In a contrasting context, less is known about the ‘psychological trajectory’ of Freud's 5-year old niece who also distinguished herself in certain respects as she matured during her abbreviated later life. She remained the subject of documentable correspondence mailed to him by his youngest daughter Anna as well as foreboding prospects articulated in a letter he subsequently wrote to an English nephew.     

The ability for dimensional analysis in preschool and retarded children: evidence from comparison, conservation, and prediction tasks

Previous findings of a developmental trend from holistic to analytic modes of processing yield to two possible interpretations—the ability to analyze into dimensions increases with age, or a production deficiency for the strategy of analyzing decreases with age. In the three studies reported here an attempt is made to elucidate which of these interpretations is the more correct by investigating the performance of preschoolers and retarded children in three tasks, all of which require dimensional analysis. The three tasks involve (a) same-different comparisons of selected dimensions of stimuli, (b) judgments of whether dimensions are conserved through transformations of objects, and (c) predictions of the outcomes of transformations that selectively modify dimensions of objects. Normal 3-year-old children and mildly retarded preadolescents make many errors on all three tasks and the patterns of these errors are predictable from holistic processing. Older groups of normal preschoolers, 4.5 to 5 years old, perform very well on the tasks, although they show some hints of remaining analytic deficits. It seems likely that the ability to analyze does undergo development in the preschool years, but that the production-deficiency interpretation also has merit, particularly for explaining developmental trends within the elementary school range.     

The termination phase of psychoanalysis as seen through the lens of the dream

The decision about when to terminate analysis has long been underpinned by a theory-driven criterion model, which may steer the analytic dialogue away from its customary activities of free association, empathic listening, and interpretation. As a remedy to this situation, the author proposes that by paying careful attention to less consciously crafted patient communications such as dreams, the analytic dyad can consider readiness to set a termination date from a perspective that is context-sensitive and less encumbered by preordained criteria. Tracing the dreams of one analysand from the vantage point of contemporary dream theory, the author demonstrates how careful attention to the dream elucidated the patient's readiness to terminate and her complex feelings about the termination process. Finally, the author challenges the notion that the termination phase is of greater evaluative than therapeutic importance, and provides clinical material as evidence that this is not the case.     

The subjective effort of everyday mental tasks: Attending,assessing, and choosing

Why are some mental tasks experienced as more effortful than others? Answers to this question about subjective effort have begun to be addressed by researchers investigating why some mental tasks are associated with more ‘elbow grease’ or ‘depletion’ than other tasks. It has been proposed that tasks such as sustained attention should be accompanied by more subjective effort than other tasks, such as assessing (e.g., counting a handful of items) or choosing randomly between two alternatives. In general, these proposals coincide with people’s intuitions regarding how effort should vary by mental task. However, little laboratory data have corroborated these conclusions. In two studies, we cataloged the relative amount of subjective effort associated with some basic and ubiquitous mental activities: attending (most subjective effort), assessing, and choosing (least subjective effort). Results support hypotheses about subjective effort. Because subjective effort is perceived to be experienced by a subject, we explored also the relationship between effort and the involvement of the ‘psychological self.’     

Complex span tasks, simple span tasks, and cognitive abilities: A reanalysis of key studies

There is great interest in the relationships between memory span tasks and cognitive abilities. However, the causes underlying their correlation remain unknown. In the present article, five key data sets were reanalyzed according to two criteria: They must consider complex span tasks (so-called working memory [WM] tasks) and simple span tasks (so-called short-term memory [STM] tasks), and they must comprise cognitive ability measures. The obtained results offer several points of interest. First, memory span tasks should be conceived from a hierarchical perspective: They comprise both general and specific components. Second, the general component explains about four times the variance explained by the specific components. Third, STM and WM measures are closely related. Fourth, STM and WM measures share the same common variance with cognitive abilities. Finally, the strong relationship usually found between memory span tasks and cognitive abilities could be tentatively interpreted by the component shared by STM and WM--namely, the capacity for temporarily preserving a reliable memory representation of any given information.     

Theory of mind tasks and executive functions: A systematic review of group studies in neurology

A growing number of studies have been addressing the relationship between theory of mind (TOM) and executive functions (EF) in patients with acquired neurological pathology. In order to provide a global overview on the main findings, we conducted a systematic review on group studies where we aimed to (1) evaluate the patterns of impaired and preserved abilities of both TOM and EF in groups of patients with acquired neurological pathology and (2) investigate the existence of particular relations between different EF domains and TOM tasks. The search was conducted in Pubmed/Medline. A total of 24 articles met the inclusion criteria. We considered for analysis classical clinically accepted TOM tasks (first‐ and second‐order false belief stories, the Faux Pas test, Happe's stories, the Mind in the Eyes task, and Cartoon's tasks) and EF domains (updating, shifting, inhibition, and access). The review suggests that (1) EF and TOM appear tightly associated. However, the few dissociations observed suggest they cannot be reduced to a single function; (2) no executive subprocess could be specifically associated with TOM performances; (3) the first‐order false belief task and the Happe's story task seem to be less sensitive to neurological pathologies and less associated to EF. Even though the analysis of the reviewed studies demonstrates a close relationship between TOM and EF in patients with acquired neurological pathology, the nature of this relationship must be further investigated. Studies investigating ecological consequences of TOM and EF deficits, and intervention researches may bring further contributions to this question.
