The relationship between disgust sensitivity, anxiety and obsessions

Three hundred participants, including volunteers from an obsessional support group, filled in questionnaires relating to disgust sensitivity, health anxiety, anxiety, fear of death, fear of contamination and obsessionality as part of an investigation into the involvement of disgust sensitivity in types of obsessions. Overall, the data supported the hypothesis that a relationship does exist between disgust sensitivity and the targeted variables. A significant predictive relationship was found between disgust sensitivity and total scores on the obsessive compulsive inventory (OCI; Psychological Assessment 10 (1998) 206) for both frequency and distress of symptomatology. Disgust sensitivity scores were significantly related to health anxiety scores and general anxiety scores and to all the obsessional subscales, with the exception of hoarding. Additionally, multiple regression analyses revealed that disgust sensitivity may be more specifically related to washing compulsions: frequency of washing behaviour was best predicted by disgust sensitivity scores. Washing distress scores were best predicted by health anxiety scores, though disgust sensitivity entered in the second model. It is suggested that further research on the relationship between disgust sensitivity and obsessionality could be helpful in refining the theoretical understanding of obsessions.     

How bumblebees first find flowers: Habituation of visual pattern preferences, spontaneous recovery, and dishabituation

Two experiments examined the exploratory behaviour of flower-naïve bumblebees. Bees were tested four times in a 12-arm radial arm maze in which they never received reward. Patterned and unpatterned stimuli were presented at the end of each corridor and the choices of the bees were recorded. We examined the effects of two variables, time and the presentation of a new stimulus, on habituation to a visual pattern. In Experiment 1, once bees had shown an unlearned preference for a pattern, and the preference had habituated, a response decrement was maintained after a confinement in the colony of two hours. After a 24 h confinement, however, the pattern preference was restored, i.e., spontaneous recovery was observed. In Experiment 2, the presentation of a new stimulus triggered renewed responding to the old pattern to which the bees had habituated, i.e., dishabituation was observed. Habituation to visual patterns is modulated by time and by exposure to new stimuli so that exploration in the face of failure to find food persists and unrewarding visual patterns are not eliminated for long as possible sources of food.     

Patient-targeted googling by psychological therapists: A narrative review of the literature and ethical implications

Background

“Patient-Targeted Googling” (PTG) refers to a healthcare professional using the Internet to discover information about a patient. The present review explores PTG by psychological therapists. The review focused on the prevalence of PTG, how often consent is sought from the patient, and the motivations for and consequences of PTG.

Method

A narrative literature review of published PTG studies was undertaken. Potentially eligible studies were identified by searching PsycINFO, PsycARTICLES, Psychology and Behavioural Sciences Collection, and MEDLINE. Results were screened for suitability for inclusion in the sample (n = 9). All studies were appraised for quality using a structured tool developed for this review.

Results

PTG prevalence rates ranged from 20% to 98%, with rates of non-consent ranging from 60% to 84%. Motivations for PTG included curiosity, to gather new information and to verify existing information. Consequences of PTG included enhancing the therapist's sense of safety and causing harm to the therapeutic relationship.

Discussion

Current literature on PTG is limited and focussed largely in the United States. This review revealed no published PTG studies including UK-based psychological therapists, as well as issues in defining and operationalising PTG. Further research is needed to understand the prevalence of PTG by UK-based psychological therapists, as well as the motivations behind, and consequences of, PTG. This evidence base will inform the development of PTG professional guidelines and training, neither of which currently exist for therapists practising in the UK. Both would be timely given the increasing move of the therapeutic frame to the online environment due to the COVID-19 pandemic.     

Incremental validity of the Minnesota Multiphasic Personality Inventory-2 and symptom checklist-90-revised with mental health inpatients

This study evaluated the incremental validity of scores from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and the Symptom Checklist-90-Revised (SCL-90-R) in a sample of mental health inpatients originally published by Archer, Griffin, and Aiduk (1995). The incremental validity of scores from the SCL-90-R primary symptom dimensions and MMPI-2 Clinical, Content, and Restructured Clinical scales was assessed in a sample of 544 mental health inpatients using conceptually related items from the Brief Psychiatric Rating Scale (BPRS) as criteria. A series of hierarchical multiple regressions indicated that scores from the SCL-90-R primary symptom dimensions exhibited limited incremental validity (Mdn DeltaR(2) = .01, range = 0-.01), whereas scores from MMPI-2 scales contributed additional information in the prediction of ratings on all but one BPRS item (Mdn DeltaR( 2) = .08, range = .04-.12).     

Effortful control, executive attention, and emotional regulation in 7–10-year-old children

In this study, self-regulation was investigated in 7- to 10-year-old children using three different measures: (1) parent and child report questionnaires measuring temperamental effortful control, (2) a conflict task assessing efficiency of executive attention, and (3) the mistaken gift paradigm assessing social smiling in response to an undesirable gift. Both efficiency in executive attention and smiling to the undesired gift increased over age. Executive attention was related to both parent-reported temperamental effortful control and smiling, suggesting links between attentional capacities, broad temperament measures, and social situations requiring attentional control.     

The postnatal development of the motor speech area: a preliminary study

This preliminary study follows the maturation of motor speech areas and their adjacent orofacial motor zones in the right and left hemispheres of the human infant from 3 months to 72 months of age. Quantitative studies of basilar dendrite patterns of layer 5 cortical pyramids are reported in 17 age-graded subjects. The sequence of developmental changes is characterized by early (3 month) prominence of orofacial motor zones over motor speech areas and of the right hemisphere over the left as expressed in total basilar dendritic length and the length of proximal order dendritic segments. The complex series of changes which follow appear to involve increase in number and marked increase in length of the developing distal order segments and possible shortening of the proximal segments. During a variable sequence of apparent growth spurts and resorptions, dendrite arborizations of the motor speech areas overtake and exceed those of orofacial musculature and the total length of dendrite systems on the left finally exceeds those on the right, although even in the most mature group, (42-72 months), distal segment length in the right motor speech area still exceeds that of the left. The early structural primacy of right-sided dendrite systems and the progressive shift to left-sided primacy is considered in the light of the presence of a long phylogenetic and ontogenetic history of gross anatomical asymmetry favoring the left side. The possibility that developmental patterns of the cortical macroenvironment and microenvironment may be dissociated with the microenvironment depending heavily on epigenetic factors receives support from recent data suggesting the existence of a time window or critical period during which primary language proficiency must be attained if normal lateralization of language function is to occur.     

Phencyclidine use in delinquent males committed to a training school

Delinquent males committed to a training school were interviewed to determine the extent and the effects of phencyclidine use. Nine of 109 (8%) drug using subjects knowingly had used phencyclidine in the past. These nine subjects were multiple drug abusers of other substances and had started taking drugs at an average age of 9.38 years which was significantly younger than non PCP users. Six of the nine PCP users had committed proven offenses against persons and in four cases violent actions were directly attributed to PCP use. Suicide attempts were made by five (55%) of the PCP users which was significantly more frequent than suicide attempts made by non PCP users.     

Relationships between magical thinking,obsessive‐compulsiveness and other forms of anxiety in a sample of non‐clinical children

Despite the obvious phenomenological similarities between magical thinking and obsessive‐compulsiveness, the relationship between them has been the subject of few empirical investigations in samples of children. The present study aimed to examine the relationship between a general epistemic stance towards magical causation and tendencies towards obsessive‐compulsiveness in a non‐clinical sample of schoolchildren. One‐hundred and two children, aged between 5 and 10 years (48 boys and 54 girls), completed questionnaire measures designed to assess magical thinking, obsessive‐compulsiveness, and other forms of anxiety. School teachers completed a measure of strengths and difficulties for each child. General belief in magical causation was correlated with all types of anxiety, not just obsessive‐compulsiveness, with significant correlations shown for boys in the sample, but not girls. General belief in magical causation contributed little to the prediction of obsessive‐compulsiveness beyond general anxiety. In this study, a general epistemic stance towards magical causation did not differentiate obsessive‐compulsiveness from other anxiety dimensions. The findings are considered in the context of developmental theories of magical and scientific causal reasoning.
