Repeated checking causes distrust in memory but not in attention and perception

Repeated checking to reduce memory distrust seems to be counterproductive: it increases memory distrust. Obsessive-compulsive (OC) patients tend to be uncertain about other cognitive domains as well, like attention and perception. In an experiment with 70 healthy participants, we tested whether perseverative checking induces distrust not only in memory, but also in attention and perception. Participants were administered a computer task in which they had to activate, deactivate, and check threat-irrelevant stimuli, and rate their confidence in memory, attention, and perception in a pre-test and post-test. In between these tests, the relevant checking group performed 20 checks of the same stimuli used in the pre- and post-test. The irrelevant checking group performed 20 checks of different stimuli. Although memory accuracy improved in both groups, repeated checking reduced confidence in memory, vividness, and detail in the relevant checking group, but not in the irrelevant checking group. A trend was found towards a decline in attentional confidence in the relevant checking group only. Perception was not affected by repetitive checking. A replication study revealed similar results of relevant checking on meta-memory, however, the trend for attentional distrust was not confirmed. The results suggest that perseveration may be domain specific, i.e., only the cognitive processes that are subject to perseveration are affected.     

Neuroticism and attachment insecurity as predictors of bereavement outcome

Adult attachment dimensions as well as the personality trait neuroticism have been shown to be related to psychological adjustment after bereavement. No investigations so far have studied the relative contribution of these constructs to grief and depression. In our study of 219 bereaved parents, the two adult attachment dimensions, attachment anxiety and attachment avoidance, were compared to the personality trait neuroticism in predicting psychological adjustment. The attachment dimensions explained a unique part over and above neuroticism, but contrary to expectations, neuroticism explained more variance than attachment dimensions. Implications are discussed.     

Can the Mind Command the Body?

People naturally intuit that an agent's ethereal thoughts can cause its body to move. Per intuitive physics; however, one body can only interact with another. Are people, then, covertly puzzled by the capacity of thoughts to command the body? Experiment 1 first confirms that thoughts (e.g., thinking about a cup) are indeed perceived as ethereal—as less detectible in the body (brain), and more likely to exist in the afterlife relative to matched percepts (e.g., seeing a cup). Experiments 2–5 show that thoughts are considered less likely to cause behavior than percepts (e.g., thinking of a cup vs. seeing one). Furthermore, mind–body causation is more remarkable when its bodily consequences are salient (e.g., moving an arm vs. brain activation). Finally, epistemic causes are remarkable only when they are ascribed to mental- (e.g., “thinking”) but not to physical states (“activation”). Together, these results suggest that mind–body interactions elicit a latent dualist dissonance.     

The neonate brain's sensitivity to repetition-based structure: Specific to speech?

Newborns are able to extract and learn repetition-based regularities from the speech input, that is, they show greater brain activation in the bilateral temporal and left inferior frontal regions to trisyllabic pseudowords of the form AAB (e.g., “babamu”) than to random ABC sequences (e.g., “bamuge”). Whether this ability is specific to speech or also applies to other auditory stimuli remains unexplored. To investigate this, we tested whether newborns are sensitive to regularities in musical tones. Neonates listened to AAB and ABC tones sequences, while their brain activity was recorded using functional Near-Infrared Spectroscopy (fNIRS). The paradigm, the frequency of occurrence and the distribution of the tones were identical to those of the syllables used in previous studies with speech. We observed a greater inverted (negative) hemodynamic response to AAB than to ABC sequences in the bilateral temporal and fronto-parietal areas. This inverted response was caused by a decrease in response amplitude, attributed to habituation, over the course of the experiment in the left fronto-temporal region for the ABC condition and in the right fronto-temporal region for both conditions. These findings show that newborns’ ability to discriminate AAB from ABC sequences is not specific to speech. However, the neural response to musical tones and spoken language is markedly different. Tones gave rise to habituation, whereas speech was shown to trigger increasing responses over the time course of the study. Relatedly, the repetition regularity gave rise to an inverted hemodynamic response when carried by tones, while it was canonical for speech. Thus, newborns’ ability to detect repetition is not speech-specific, but it engages distinct brain mechanisms for speech and music.

Research Highlights

• The ability of newborns’ to detect repetition-based regularities is not specific to speech, but also extends to other auditory modalities.
• The brain mechanisms underlying speech and music processing are markedly different.

     

Dream recall, dream length, and sleep duration: state or trait factor

Longer sleep duration should be related to dream recall (longer REM sleep), but previous findings regarding the relationship between habitual sleep duration and dream recall frequency have been conflicting, whereas experimental manipulation of sleep duration yielded a significant effect. The analysis of diaries kept by the 444 participants over 14 days indicated that intra-individual fluctuations and interindividual differences in sleep duration affect dream recall.     

Eye movements during recall of aversive memory decreases conditioned fear

Cognitive-behavioral therapy for anxiety disorders typically involves exposure to the conditioned stimulus (CS). Despite its status as an effective and primary treatment, many patients do not show clinical improvement or relapse. Contemporary learning theory suggests that treatment may be optimized by adding techniques that aim at revaluating the aversive consequence (US) of the feared stimulus. This study tested whether US devaluation via a dual task – imagining the US while making eye movements – decreases conditioned fear. Following fear acquisition one group recalled the US while making eye movements (EM) and one group merely recalled the US (RO). Next, during a test phase, all participants were re-presented the CSs. Dual tasking, relative to the control condition, decreased memory vividness and emotionality. Moreover, only in the dual task condition reductions were observed in self-reported fear, US expectancy, and CS unpleasantness, but not in skin conductance responses. Findings provide the first evidence that the dual task decreases conditioned fear and suggest it may be a valuable addition to exposure therapy.     

Emotional intelligence (EI), conflict resolution patterns,and relationship satisfaction: Actor and partner effects revisited

This study tested for actor and partner effects in the relationship between ability-based EI and adaptive marital relationships and satisfaction employing a standard dyadic design involving 100 young heterosexual couples. Participants were assessed on the MSCEIT along with measures of conflict resolution patterns and perceived marital satisfaction. A series of path analyses provided support for actor effects—but not partner effects—in the association of EI, assessed as ability, and marital variables. Overall, the data provide only partial support for the common claim and some prior research suggesting that EI plays a pivotal role in marital relationships.     

Is there less to social anxiety than meets the eye? Emotion experience,expression, and bodily responding

Emotions are widely held to involve changes in experiential, behavioural, and physiological systems. It is not clear, however, just how tightly coupled these changes are during emotional responding. To examine this issue, we induced social anxiety in 47 high trait social anxiety (HTSA) and 50 low trait social anxiety (LTSA) participants using an impromptu speech paradigm. We assessed anxiety experience, behaviour, perceived physiological activation, and actual physiological activation. HTSA participants felt more anxious, perceived greater physiological activation, and exhibited more anxiety behaviour than LTSA participants. Unexpectedly, the two groups did not differ in objectively measured physiological responding. Internal analyses indicated that for both HTSA and LTSA participants, anxiety experience was associated with perceived physiological activation, but not with actual physiological responding. These results suggest that anxiety experience and perceived physiological activation may be less tightly coupled with actual physiological responses than is typically thought.     

The fate of the oedipus complex: Dissolution or waning

Abstract

Fried R. Personal and Classical Myth; A Confrontation on the Acropolis. Int Forum Psychoanal 1997;6:715. Stockholm, ISSN 0803-706X.

On his only visit to Greece, Sigmund Freud experienced brief but unsettling feelings of alienation as he stood on the Acropolis. Haunted by this experience, Freud did not succeed in analyzing it to his own satisfaction until 32 years after the event, in 1936. His interpretation, that he had felt guilt about superseding his father, did not convince most of the critics who have commented on it. The aim of this essay is to demonstrate that while Freud's critics were right in sensing that his explanation was only partial, none were able to decipher his secret. Prominent among the reasons for these repeated failures was lack of acquaintance with the Acropolis itself. Anyone standing where Freud stood becomes enabled to understand otherwise incomprehensible details of his essay. Seeing what Freud saw, however, still is not enough unless one also attempts to acquire some of his knowledge of archaeology and mythology. His competence in these areas made him aware of contradictions (e.g. between classical and archaic architecture and myth) that do not trouble the casual tourist. But his knowledge also furnished him with the tools for mastering his anxiety, turning fear of death into confidence in immortality, and gratifying desires even more ambitious than that of superseding his father.
