Intrusion errors in visuospatial working memory performance

This study tested the hypothesis that failure in active visuospatial working memory tasks involves a difficulty in avoiding intrusions due to information that is already activated. Two experiments are described, in which participants were required to process several series of locations on a 4 x 4 matrix and then to produce only the final location of each series. Results revealed a higher number of errors due to already activated locations (intrusions) compared with errors due to new locations (inventions). Moreover, when participants were required to pay extra attention to some irrelevant (non-final) locations by tapping on the table, intrusion errors increased. Results are discussed in terms of current models of working memory functioning.     

What people believe about memory

Two representative samples of adult Norwegians (n=2000) were asked a set of general and specific questions regarding their beliefs and opinions about human memory. The results indicate that on many questions, such as time of the earliest memories, inhibiting effects of collaboration, and memory for dramatic versus ordinary events, the views of the general public concurred with current research findings, and people in general had realistic views about their own memory performance. On other questions, such as the reliability of olfactory as compared with visual and auditory memory, the memory of small children in comparison with that of adults, the likelihood of repression of adult traumatic memories, and on more general questions such as the possibility of training memory and the capacity limitations of long-term memory, a large proportion of the participants expressed views that are less supported by scientific evidence. Implications of these findings are briefly discussed.     

Visual but not spatial working memory deficit in children with spina bifida

Twenty children with spina bifida and twenty controls were assessed on a battery of visuospatial working memory tests. Children with spina bifida performed as well as the control group in the visuospatial test and in the forward and backward versions of the Corsi test, but were impaired in the 'House Visual Span.' This test, designed in our lab, provides specific information regarding visual ability to discriminate between pictorial targets and lures, and requires specific visual processing of stimuli. These results are discussed in terms of working memory models and are viewed as supporting the distinction between the visual and spatial components of working memory.     

Reality monitoring and resistance to forgetting under short delay intervals

In three experiments, participants were asked to perform simple action statements or to imagine performing the actions in a single study session. In a test session that occurred 1 hr, 24 hr, 48 hr (Experiments 1a and 1b), or 1 week later (Experiments 2 and 3), participants were instructed to tell whether the action statement had been carried out or imagined. The primary finding was that, overall, recognition and reality monitoring showed a comparable rate of forgetting. The results add evidence to the hypothesis that, also after long retention delays, discrimination between an internal and an external source may not be inferior to item recognition. A new theoretical proposal to account for these findings is outlined.     

Existential crises in two religious patients: Vicissitudes of faith and the emergence of the true self

The authors present two clinical cases involving an existential crisis which led the patients to lose what had been the foundation in their lives, their faith. Although the therapeutic settings differ – the first patient had a few psychotherapy sessions following a psychotic episode with a mystical background, while the second was in the final stage of analytic treatment – the authors highlight how in both clinical cases a loss of faith becomes a total and urgent crisis of the Self. The fracture which ensues seems to generate an intense engagement of the body which, paradoxically during a loss of faith, induces an experience of ecstasy of the kind that has traditionally been reported. In the first case the experience of ecstasy was lived first‐hand by the patient who thereafter redefined the psychotic breakdown as a “moment of truth”; whereas the second patient, through a deep projective identification, induces an eerie countertransferential feeling of ‘metaphysical’ shortfall in the agnostic psychoanalyst, triggering bewilderment, physical discomfort and awe in him. In both cases the authors believe that the notable somatic involvement may be correlated to a potentially profound and unprecedented contact with the True Self.     

M by Fritz Lang (Germany, 1931) Phenomenology of Evil: a serial killer and his social group

In 1931 an unknown murderer of little girls (Peter Lorre) is terrorizing the city of Berlin. We see him entice a new victim, the little Elsie Beckmann, who is coming home from school: whistling a tune by Grieg, he buys her a balloon from a blind beggar. When her corpse is discovered, the police undertake a major mobilization aimed at seeking the serial killer in the criminal underworld; meanwhile, the ever more terrified population starts to see the dangerous murderer in everyone. Since the roundups and incursions into the seediest parts of town disturb the gangsters’ activities, the leaders of organized crime, headed by Schränker (Gustav Gründgens), take it upon themselves also to hunt down the solitary child‐killer, engaging the community of beggars. Every corner of the city is catalogued and sifted by the dual activity of the police and the gangsters. The ‘monster’, a former psychiatric patient, mild and harmless in manner, is finally tracked down via two parallel routes: the clue of a cigarette packet enables Inspector Lohmann (Otto Wernicke) to track down the serial killer's address, while the blind beggar recognizes the whistled tune. The murderer is identified by a ‘slap’ from a young criminal which leaves an M marked in chalk on a shoulder of the man's overcoat. Thus he is caught and undergoes a kind of trial at the hands of the gangsters who tie him up in order to lynch him, but they are interrupted by the arrival of the forces of law and order.     

The effects of the constancy of location and order in working memory visual–phonological binding of children with dyslexia

It has been suggested that children with dyslexia have difficulties in visual–phonological working memory (WM) binding, supporting the hypothesis that this ability is crucial in the formation of associations between written forms and phonological codes required by reading. However, research on this topic is currently scarce and has not clarified to what extent binding may be supported by spatial and temporal information. The present study examined visual–phonological WM binding performance in a group of children with dyslexia compared to a control group of typically developing children matched for age, gender, and grade. Children had to memorize ephemeral associations between meaningless shapes and nonwords, with stimuli presented in either fixed or variable spatial locations, and in either fixed or variable temporal order across trials; performance was assessed using a recognition task. Results showed that children with dyslexia have a deficit in visual–phonological WM binding in every presentation condition and that, unlike control children, they are not able to use fixed spatial locations as an aid to bind information. Crucially, however, children with dyslexia still benefit from the presentation of stimuli in a fixed temporal order. These findings support the hypothesis that a WM binding deficit is crucial in children with dyslexia, and have potential implications for treatment strategies.     

The factor structure of the Inventory of Parent and Peer Attachment (IPPA): A survey of Italian adolescents

Despite the intensive use of the Inventory of Parent and Peer Attachment (IPPA), a measure of attachment which centres on individual differences in adolescents and their ability to evaluate their relationships with parents and peers, the factor structure of the inventory requires further investigation. This study of 1059 Italian adolescents compared the three models which are discussed in the literature: the one-factor model (attachment security), the two-factor model (trust-communication and alienation) and the three-factor model (trust, communication and alienation), and examined the influences of age and gender on the IPPA’s scores. Our findings provide support for the reliability of the latest and longer version of the IPPA (75-item). Factor analysis showed that the three-factor model had the best fit, although the three dimensions are strongly interrelated. Sixteen year olds had lower attachment security to their fathers than the results of the other adolescent age groups. Males reported lower alienation scores than females in the paternal form, while females had higher attachment security, trust and communication scores than males in the peers form.
