Temporal processing and psychosis proneness

Two measures of temporal processing: critical stimulus duration (CSD) and visual backward masking (VBM), were examined in a group of normal subjects whose predisposition to psychosis was assessed using the psychoticism (P) scale from Eysenck's Personality Questionnaire. The current study employed the method of constant stimuli with a two-alternative forced choice responding to reduce the variability in CSD-data. Higher P scorers required a significant longer target stimulus duration in order to correctly identify the stimulus than lower P scorers. These results suggest that subjects prone to psychosis possess a relatively less sensitive temporal processing system than low P scorers. Performance in the subsequent masking phase revealed no evidence of a VBM deficit. It was not possible to explain this pattern of results in terms of task difficulty. The findings were discussed in terms of potential inadequacies in previous calculations of CSD. This possibility requires further testing before the backward masking deficit can be adopted as a trait marker for schizophrenia.     

Temporal experience in mania

The paper examines both the phenomenology of the manic self as well as critical aspects of manic neurobiology, focusing, with respect to both domains, on manic temporality. We argue that the distortions of lived time in mania exceed mere acceleration and are fundamental for manic affectivity. Mania involves radical acceleration and radical asynchronicity, which result in an instantaneous existence. People with mania rebel against the facticity of reality and suffer from an existential leap towards the future, in which the self abandons normal temporal boundaries. Excerpts from the interviews with persons with mania who experienced psychosis illustrate this phenomenon. Commenting upon disrupted circadian rhythms in mania and the role of lithium in its treatment the paper posits manic temporality as the link through which manic phenomenology and manic neurobiology intertwine.     

Temporal experience as metaphysically lightweight

Experience is the most primitive kind of intentional contact with reality. Metaphysical inquiry is one of the heights of human thought. It would not be surprising if experience was often silent on metaphysics, failing to offer support to one metaphysical disputant over the other, forcing them to fall back on nonexperiential considerations. I argue that the dispute between A- and B-theorists about time is a dispute about which experience is silent. B-theorists have typically conceded that the manifest image of time conflicts with how time turns out to be, on their own view of time. They have offered an array of accounts of why that conflict should not worry us. I argue here that these accounts are unconvincing. I also argue that they are unnecessary. Nothing about how time is experienced conflicts with B-theory. An independently plausible method for discovering what properties experience represents—the method of phenomenal contrast—implies that experience does not favor A-theory over B-theory.     

Temporal memory of emotional experience

The few studies that have investigated judgments of time have suggested that the memory of duration is distorted more for emotional events than for neutral events, while in contrast there is abundant evidence that other aspects of memories of emotional events are more accurate. To reconcile this apparent discrepancy, we used a procedure in which the participants learned a standard duration over several trials under three emotional conditions: a threatening, a nonthreatening, and a neutral control condition. They were then tested either immediately or 24 h after learning. In this test phase, they had to indicate whether presented comparison durations were or were not the same as the previously learned standard duration. We found that durations were recalled better in the emotional than in the neutral condition, and that this occurred to a greater extent in the threatening than in the nonthreatening condition. Arousing emotions thus enhanced temporal memory, just as they enhance memory for other aspects of emotional events.

Mediation of the stigma in the influence of negative symptomatology over recovery in psychosis

Background/Objective: The interest in recovery processes in psychotic disorders has boosted the necessity of knowledge about the factors that could influence in such recovery. Negative symptomatology and the stigma have been negatively linked to the recovery process in psychosis. The aim of this investigation is to improve the understanding of how the recovery process is affected by negative symptomatology based on the analysis of the mediating effects of the internalized stigma. Method: The sample was composed of 114 people that had experienced, at some point in their life, at least one clinically relevant psychotic episode. CAPE-42, STORI and ISMI were used for the evaluation. The macro PROCESS for SPSS was used. The indirect effect was calculated using 10.000 samples of bootstrap for the bootstrap confidence intervals (IC) corrected for bias. Results: The results show that the influence of negative symptomatology predicts the stigmatization of the person regarding his disorder. This predicts a negative influence in the recovery process of the psychosis. Conclusions: These results back the importance of adding the reduction of the stigma as a specific strategy to improve the recovery process in psychotic disorders.     

Learning from women with psychosis

The article describes psychoanalytic reflections in the work of a consultant psychiatrist responsible for a recently developed female intensive care unit. The manifestations of aggression were observed to be different from that of male patients. The behavioural manifestation of aggression by women was linked to the themes of secrets, and of hidden aggression, which are described in the analytic literature as feminine characteristics. The relationships between women as sibling inpatients and with female staff may explain some of the difficulties in managing aggression. Hidden aggression in the dyad of female-to-female transferences and countertransference may contribute to problems in all female inpatient settings. Bringing together the themes of psychosis and of women from a psychoanalytic perspective, the author suggests that the care pathway leading to transfer to the intensive care unit may exacerbate psychotic symptoms in acute states, due to specific vulnerabilities of women. The provision of specialized inpatient services for women may be more therapeutic if female development and the nature of their relationships were better understood.     

Adult visual experience promotes recovery of primary visual cortex from long-term monocular deprivation

Prolonged visual deprivation from early childhood to maturity is believed to cause permanent visual impairment. However, there have been case reports of substantial improvement of binocular vision in human adults following lifelong visual impairment or deprivation. These observations, together with recent findings of adult ocular dominance plasticity in rodents, led us to re-examine whether adult primary visual cortex (V1) is capable of any recovery following long-term monocular deprivation starting in development. Using mice as a model, we find that monocular deprivation from early development to mature ages (well past the critical period) severely impaired binocular vision by reducing the amplitude of responses elicited by stimulation of the deprived eye. Surprisingly, we find little effect on nondeprived eye responses. Restoration of binocular vision in mature adults yields modest but significant improvement of visual responses in V1. Remarkably, we find that when binocular vision is followed by occlusion of the nondeprived eye, visual responses in V1 recover almost fully, as measured by visual evoked potential amplitude, spatial frequency threshold, and single-unit activity. We conclude that adult V1 can recover from long-term deprivation when provided with an optimal regimen of visual experience.     

Temporal changes in the affective experience of new fathers and their spouses

Our aim was to study temporal changes in fathers' affective experience during the first year of parenthood. For comparison, data also were collected from their spouses. Fifty‐five Israeli couples comprised the initial sample, and both partners were interviewed during the prepartum period and at 3, 6, and 12 months' postpartum. Measures of emotionality, positive affect, negative affect, and mood regarding self, infant, and spouse/marriage were derived by finely coding parents' answers to interview questions. Analyses show that, for fathers and mothers, time effects were most substantial between the prepartum period and 3 months postpartum, and most of the changes were in a positive direction. Fathers and mothers showed continuity in positive affect and in negative affect, respectively. Overall, the sample experienced heightened positive affect and more positive moods after the birth of their infant than prior to it.     

Parental object representations,attachment to God,and recovery among individuals with psychosis

This study explored the relationships between object representations of mother and father and recovery among outpatients with psychotic disorders, and examined the role of attachment to God in moderating those relationships. A total of 46 outpatients diagnosed with schizophrenia or schizoaffective disorder participated. Benevolent representations of mother and father were associated with recovery whereas punitive representations were negatively associated with recovery. Secure attachment to God amplified the association between benevolent representations of father and recovery. Secure attachment to God was found to buffer the relationship between mild-to-moderate punitive parental representations and recovery; however, this relationship was not evident for those with the most punitive parental representations. Directions for future research and clinical implications are discussed.     

Temporal integration in structure from motion

A temporal integration model is proposed that predicts the results reported in 4 psychophysical experiments. The main findings were (a) the initial part of a structure-from-motion (SFM) sequence influences the orientation evoked by the final part of that sequence (an effect lasting for more than 1 s), and (b) for oscillating SFM sequences, perceived slant is affected by the oscillation frequency and by the sign of the final gradient. For contracting optic flows (i.e., rotations away from the image plane), the sequence with the lowest oscillation frequency appeared more slanted; for expanding optic flows (i.e., rotations toward the image plane), the sequence with the highest oscillation frequency appeared more slanted.     

Attachment experience and cortisol recovery from romantic conflict among young Chinese couples: A dyadic analysis

Using a sample of young adults, the present study investigated how the participants' attachment to romantic partners was related to that with their parents and peers and how this specific attachment experience was associated with their physiological stress response. We examined 121 pairs of young Chinese (N = 242) heterosexual couples (men's age: 22.26 ± 2.40; women's age: 21.62 ± 2.22) and their attachment to parents, peers, and romantic partners as well as their cortisol recovery from romantic conflict. Robust actor–partner interdependence mediation models showed that women's insecure parental and peer attachment was associated with blunted cortisol recovery from romantic stress through their fearful attachment with romantic partners, whereas men's insecure parental and peer attachment was associated with their partners' adaptive cortisol recovery from romantic stress through their fearful romantic attachment. These findings suggested that women's hypothalamic–pituitary–adrenal-axis functioning seemed to be more strongly associated with their own and their partners' attachment relationships compared to men.

Temporal focus,temporal distance,and mind-wandering valence: Results from an experience sampling and an experimental study

When mind-wandering, people may think about events that happened in the past, or events that may happen in the future. Using experience sampling, we first aimed to replicate the finding that future-oriented thoughts show a greater positivity bias than past-oriented thoughts. Furthermore, we investigated whether there is a relation between the temporal distance of past- and future-oriented thoughts and the frequency of positive thoughts, a factor that has received little attention in previous work. Second, we experimentally investigated the relation between temporal focus, temporal distance, and thought valence. Both studies showed that future-oriented thoughts were more positive compared to past-oriented thoughts. Regarding temporal distance, thoughts about the distant past and future were more positive than thoughts about the near past and future in the experiment. However, the experience sampling study did not provide clear insight into this relation. Potential theoretical and methodological explanations for these findings are discussed.     

A pilot study exploring compassion in narratives of individuals with psychosis: implications for an attachment-based understanding of recovery

There is increasing recognition that cultivating compassion for oneself and others can act as an antidote to feelings of threat, shame, humiliation and paranoia. This study aimed to explore the further development of a narrative-based measure of compassion. We hypothesised that greater compassion would be associated with lower levels of positive symptoms, negative symptoms, cognitive disorganisation, excitement and emotional distress. Participants were 29 individuals with psychosis. Greater narrative compassion was associated with less negative symptoms, less cognitive disorganisation and less excitement. We found no correlations between narrative compassion and the Self-Compassion Scale. Notwithstanding the methodological problems of our study, our findings have important implications for developing an attachment-based understanding of compassion and the use of compassion to support recovery from complex mental health problems such as psychosis.
