Online we are all able bodied: Online psychological sense of community and social support found through membership of disability‐specific websites promotes well‐being for people living with a physical disability

People with a physical disability are a population who for a number of reasons may be vulnerable to social isolation. Research into Internet‐based support sites has found that social support and an online sense of community can be developed through computer mediated communication channels. This study aims to gain an understanding of the benefits that membership of disability‐specific online communities may have for people with a physical disability. An online survey was administered to a sample of users of such sites (N = 160). Results indicated that users did receive moral support and personal advice through participating in such online communities. Further, results indicated that online social support and feeling a sense of community online were positively associated with participants' well‐being in the areas of personal relations and personal growth.

When wanting and fearing go together: The effect of co‐occurring social approach and avoidance motivation on behavior,affect, and cognition

Three studies investigated the association of social approach and avoidance motivation with cognition, behavior, emotions, and subjective well‐being. Study 1 (N = 245), a correlative self‐report study, showed that approach and avoidance motivation mediated the effects of adult attachment‐styles on social anxiety. A secure attachment‐style was associated with co‐occurring approach and avoidance motivation. Study 2, a social‐interaction study (N = 38), revealed an association of avoidance motivation with a negative experience and passive behavior, and approach motivation with a positive experience and active behavior. Interestingly, the interaction of approach and avoidance motivation predicted engaged behavior and a positive emotional experience. Study 3 (N = 203), an online survey, showed that subjective well‐being was negatively associated with high avoidance motivation, irrespective of the strength of approach motivation. Taken together, the studies show that social approach and avoidance motivation interact in predicting positive experiences and social behavior in a concrete social situation. However, from the long‐term perspective, the negative consequences of social avoidance motivation seem to prevail when approach and avoidance motivation co‐occur.

Bicultural identities: The interface of cultural, personality, and socio-cognitive processes

This paper presents recent work examining the meaning and impact of individual variations in the way bicultural individuals organize their two cultural identities, a construct that we call Bicultural Identity Integration (BII). While biculturals high on BII describe their two cultural identities as ‘compatible’ (fluid and complementary), biculturals low on BII experience them as largely ‘oppositional’ (i.e., conflicting and disparate). We first report experimental evidence for how variations in BII moderate biculturals’ socio-cognitive behavior, specifically, the way in which bicultural individuals process cultural knowledge and use it to interpret social behavior. We then report structural equation modeling findings that elucidate some important personality, contextual, and performance predictors of BII. Finally, we conclude with a brief discussion of how the study of bicultural identities provides an ideal ground for the integration of cultural and personality psychology.     

Using a flipped spoon to decrease packing in children with feeding disorders

We evaluated the effects of redistribution and swallow facilitation with a flipped spoon on packing in 2 children with a feeding disorder. For both participants, packing decreased when we implemented the flipped spoon treatment package. Mechanisms responsible for behavior change and areas of future research are discussed.     

Can Inattention/Overactivity Be an Institutional Deprivation Syndrome?

Elevated rates of attention deficit and overactivity have been noted previously in samples of institution-reared children. This study examined the hypothesis that inattention/overactivity(I/O) might constitute a specific deprivation syndrome. One hundred and sixty five children adopted at varying ages (e.g., 0–42 months of age) into the UK following severe early deprivation were compared with 52 within-UK adoptees who did not suffer deprivation. The children were rated by teachers and parents on levels of I/O, conduct difficulties, and emotional difficulties using the Revised Rutter Scales. Data were collected at age 6 for the entire sample and at age 4 for the UK adoptees and for the subsample of Romanian children who entered the UK before the age of 2 years. Mean level analyses suggested a significant effect of duration of deprivation on I/O, but not on conduct or emotional difficulties. The effects of duration of deprivation were specific to I/O and were not accounted for by low birth weight, malnutrition, or cognitive impairment. Levels of I/O correlated with attachment disturbances. Furthermore, the effects of duration of deprivation on I/O did not attenuate over time. We conclude that I/O may well constitute an institutional deprivation syndrome, but that the type of attention deficit and overactivity exhibited by these children may present a different clinical picture from that of ordinary varieties of attention deficit disorder or hyperkinetic syndrome.     

Oxidative stress in university students during examinations

Mental stress in psychiatric disease and in daily life contributes to oxidative stress in the body. In this study we investigated a connection between possible psychological stress caused by university undergraduate examinations and oxidative stress experienced by our test subjects. Some parameters of oxidative stress (single strand breaks of DNA in lymphocytes, sensitivity to lipid oxidation and antioxidant status) were studied in medical students on the day of the examination (stress condition) and compared with the same parameters obtained from the same students during the term between two examination periods (non-stress condition). The results show that in the stress condition oxidative damage to DNA and sensitivity to lipid oxidation were significantly increased (p<0.05) when compared with the same parameters in "non-stress" conditions. A significant decrease in plasma antioxidant activity (p<0.05) in students that were under stress was observed. These results suggest that during university examinations students are under increased oxidative stress.     

Protein synthesis-dependent long-term memory induced by one single associative training trial in the parasitic wasp Lariophagus distinguendus

Protein synthesis-dependent long-term memory in Apis mellifera and Drosophila melanogaster is formed after multiple trainings that are spaced in time. The parasitic wasp Lariophagus distinguendus remarkably differs from these species. It significantly responds to the artificial odor furfurylheptanoate (FFH) in olfactometer experiments, when this odor was presented during one single training trial, consisting of one sequence of host recognition behavior on a wheat grain infested by its hosts. Feeding wasps with actinomycin D erases the learned response 24 h after the training, demonstrating that protein synthesis-dependent long-term memory has been formed in L. distinguendus already after one single training.     

Serotonergic dysfunction: Brain imaging and behavioral correlates

Identification of gene-environment and gene-gene interactions has become increasingly important in understanding psychiatric disorders. Dysfunction of central serotonergic neurotransmission has been implicated in alcoholism, depression, and anxiety. We review the literature on nonhuman primates that assesses the interaction between the genetic constitution of the regulatory region of the serotonin transporter (5-HTT) and environmental factors. Prospective studies in nonhuman primates that underwent social stress found a reduction of the serotonin turnover rate among carriers of one or two short alleles in a functional polymorphism of the 5-HTT promoter. In these primates, brain imaging studies showed a relative increase in the availability of raphe serotonin transporters. A low serotonin turnover rate and a high availability of serotonin transporters were associated with reduced response to excessive alcohol intake, anxiety, and impulsive aggression. Animal experiments point to a relationship between serotonergic dysfunction, negative mood states, and excessive alcohol intake, which may in part be mediated by reduced alcohol-induced sedation.
