THE INFLUENCE OF INTENSITY AND DURATION OF ELECTRICAL STIMULATION ON SUBJECTIVE VARIABLES

The unpleasantness and subjective duration of an A.C. current of 50 c/sec applied to two fingers was scaled by subjects using the method of magnitude estimation. Stimulation was varied with regard to both intensity and duration. It was found that (1) unpleasantness increased logarithmically with stimulus duration, (2) unpleasantness was a power function, with the exponent 1.5, of stimulus intensity, (3) subjective duration was essentially linearly related to stimulus duration, and (4) subjective duration increased logarithmically with intensity of stimulation.     

To Identify or Not To Identify? National Disidentification as an Alternative Reaction to Perceived Ethnic Discrimination

This study was a longitudinal investigation of the psychological and attitudinal consequences of perceived ethnic discrimination and ethnic and national identification among immigrants in an 8-year follow-up study with panel data. The participants were 293 immigrants in Finland coming from the former Soviet Union. The results supported the Rejection-Disidentification Model (RDIM) proposed in this study; perceived discrimination resulted in national disidentification, which, in turn, increased hostile attitudes towards the national out-group. Contrary to prevalent assumptions in the literature, long-term psychological well-being was not determined by the absolute level of discrimination experienced in the past. However, it was influenced by an increase in those experiences over time, and evidence was also obtained for the reciprocal relationship between perceived discrimination and well-being. The results of the study were discussed in terms of the further development of the theoretical models explaining the role of identification in relationships between perceived discrimination, attitudes towards the national out-group and well-being among multiple-identified minority members.     

Application of Sustainable Habitat: What is the Appropriation and Utilisation of Equipment After Energy‐Saving Renovations in Social Housing?

To reduce energy consumption, technical equipment alone is not sufficient. Adjustment of behaviours so that equipment is used appropriately is also necessary. Numerous studies have shown how difficult it is to change behaviours and how many factors are involved. The aim of this study is to identify the psychosocial factors facilitating or inhibiting energy‐saving behaviours in the appropriation of energy‐saving equipment by residents. Forty‐one semi‐directive interviews were conducted with tenants of terraced houses (12 people) and flats (29 people) located in the same residential area in a French city. The blocks of flats and terraced houses are managed by a proprietor of social housing. The results of a categorical content analysis highlight the importance of the relationship between tenants and proprietor and tenants' low motivation concerning the energy‐saving renovations. Consequently, we argue for the importance of favouring active participation by tenants in order to promote acceptance and appropriation of the new equipment. Furthermore, both the social and physical contexts of residents must be taken into account and energy saving must be integrated into other types of environmental behaviours in the neighbourhood in order to improve coherence and credibility.

Overgeneral memory and suppression of trauma memories in post-traumatic stress disorder

The study investigated the relationship between the suppression of trauma memories and overgeneral memory in 42 assault survivors with and without PTSD. Overgeneral memory (OGM) was assessed with a standard autobiographical memory test (AMT). Participants completed two further AMTs under the instructions to either suppress or not suppress assault memories, in counterbalanced order. Participants with PTSD retrieved fewer and more general memories when following the suppression instruction than participants without PTSD, but not under the control instruction. OGM correlated with PTSD symptom severity, and measures of cognitive avoidance. The results are discussed with reference to current theories of overgeneral memory and its possible relationship with PTSD.
