Exploring how people respond to conflicts between self‐interest and fairness: Influence of threats to the self on affective reactions to advantageous inequity

Two studies examined how people deal with conflicts between their self‐interest concerns and their striving for fairness. Specifically, the affective reactions to outcome arrangements in which people receive better outcomes than comparable other persons, were studied. These arrangements of advantageous inequity constitute situations in which fairness and self‐interest concerns are in conflict. Building on the social psychology of the self, it was predicted, and found, in both field and lab experiments that when people experience a self‐threat, they react more positively to arrangements of advantageous inequity than when not experiencing this threat. This supports the view that people's need for positive information about their selves is an important factor in the underlying psychological processes of the way that people deal with conflicts between their fairness and self‐interest concerns.     

Home cage testing of delay discounting in rats

Testing rodents in their home cages has become increasingly popular. Since human intervention, handling, and transport are minimized, behavior can be recorded undisturbed and continuously. Currently existing home cage systems are too complex if only relatively simple operant-learning tests are to be carried out in rats. For that purpose, a new low-cost computer-controlled operant panel was designed, which can be placed inside the home cage. A pilot study was carried out, using an intolerance-to-delay protocol, classically developed for testing behavioral impulsivity. Male adult rats were tested in their home cages, containing the operant panel provided with nosepoking holes. Nose poking in one hole resulted in the immediate delivery of one food pellet (small-soon, SS), whereas nose poking in the other hole delivered five food pellets after a delay (large-late), which was increased progressively each day (0–150 sec). The two daily sessions, spaced 8 h apart, lasted 1 h each, and the time-out after food delivery was 90 sec. A clear-cut shift toward preference for SS, which is considered a classical index of cognitive impulsivity, was shown at the longest delay. It is noteworthy that rats shifted when the delay interval was longer than the mean intertrial interval—that is, when they experienced more than one delay-equivalent odds against discounting (see Adriani & Laviola, 2006). The shortened training (2 days) and testing (5 days) phases, as allowed by prolonged and multiple daily sessions, can be advantageous in testing rodents during selected short phases of development. Current research is focusing on further validation of this and similar protocols.     

Reading Ability and the Use of Context in Orthographic Information Processing

Reading ability and context use in orthographic processing during silent reading were investigated. Poor readers and reading-level matched controls were presented target words containing a letter substitution in two contrasting context conditions. The hypothesis was that presenting a word in a highly predictable context would induce readers to proceed through the text without completely processing orthographic units at lower processing levels in the hierarchy (e.g., constituent letters). This general context effect was found. Normal and poor readers did not differ in context dependency. Poor readers more often missed substitutions, regardless of context. Poor readers also processed orthographic information less accurately. Target letters located in final word position were missed most often. Substitutions located in high bigram-frequency letter clusters were more often missed, and this effect was independent of intraword location. The implications of these results for understanding poor readers' basic reading problems are discussed.     

Appetitive and aversive olfactory learning induce similar generalization rates in the honey bee

Appetitive and aversive learning drive an animal toward or away from stimuli predicting reinforcement, respectively. The specificity of these memories may vary due to differences in cost–benefit relationships associated with appetitive and aversive contexts. As a consequence, generalization performances may differ after appetitive and aversive training. Here, we determined whether honey bees show different rates of olfactory generalization following appetitive olfactory conditioning of the proboscis extension response, or aversive olfactory conditioning of the sting extension response. In both cases, we performed differential conditioning, which improves discrimination learning between a reinforced odor (CS+) and a non-reinforced odor (CS?) and evaluated generalization to two novel odors whose similarity to the CS+ and the CS? was different. We show, given the same level of discriminatory performance, that rates of generalization are similar between the two conditioning protocols and discuss the possible causes for this phenomenon.     

A Population‐Based Comparison of Female and Male Same‐Sex Parent and Different‐Sex Parent Households

This investigation compared Dutch same‐sex parent and different‐sex parent households on children's psychological well‐being, parenting stress, and support in child rearing. It was also assessed whether associations among children's well‐being, parenting stress, and support in child rearing were different in the two household types. Data were based on a nationally representative survey (N = 25,250). Matching was used to enhance similarity in background characteristics between both types of families. Parental and child characteristics were matched for 43 female same‐sex parent, 52 male same‐sex parent, and 95 different‐sex parent households with offspring between 5 and 18 years old. No significant differences were found on children's well‐being, problems in the parent–child relationship, being worried about the child, or the use of formal and informal support between mothers in same‐sex and different‐sex parent households or for fathers in same‐sex and different‐sex parent households. Regarding perceived confidence in child rearing, fathers in same‐sex parent households and mothers in different‐sex parent households felt less competent than their counterparts. Neither the associations between children's well‐being and the predictors (parenting stress variables) nor those between support and the predictors (parenting stress and children's well‐being) differed along household type. In this population‐based study, the similarity in child outcomes regardless of household type confirms the results of prior investigations based on convenience samples. These findings are pertinent to family therapists, practitioners, court officials, and policymakers who seek information on parenting experiences and child outcomes in female and male same‐sex parent families.     

Stigma by Association Among Family Members of People with a Mental Illness: A Qualitative Analysis

People with mental illness are not the sole recipients of stigmatisation; their immediate family members may be subjected to stigma by association. Through semi‐structured interviews, we investigated experiences of stigma by association among 23 immediate family members of people with mental illness. Participants reported experiencing stigma by association from community members, mental health professionals, and civil servants. Familial relationship, co‐residence, and the gender of participants appeared to play a role in their stigma experiences; parents and spouses reported different manifestations of stigma by association than siblings and children, participants who lived together with their family member with mental illness reported increased experiences of stigma by association, and in contrast to male participants, female participants reported others thinking they are overprotective and as such perpetuated, maintained, or sustained their family members' mental illness. The relevance of these factors points to the need for tailored education and emotional support provision to family members of people with mental illness. Moreover, in‐service training for mental health professionals should include the development of relevant social skills that enable the recognition of familial relationships and roles, and family members' fears, concerns, and problems.

Exploring the relation between visual mental imagery and affect in the daily life of previously depressed and never depressed individuals

Previously depressed individuals experience disturbances in affect. Affective disturbances may be related to visual mental imagery, given that imagery-based processing of emotional stimuli causes stronger affective responses than verbal processing in experimental laboratory studies. However, the role of imagery-based processing in everyday life is unknown. This study assessed mental imagery in the daily life of previously and never depressed individuals. Higher levels of visual mental imagery was hypothesised to be associated with more affective reactivity to both negatively and positively valenced mental representations.

This study was the first to explore mental imagery in daily life using experience sampling methodology. Previously depressed (n?=?10) and matched never depressed (n?=?11) individuals participated in this study. Momentary affect and imagery-based processing were assessed using the “Imagine your mood” smartphone application. Participants recorded on average 136 momentary reports over a period of 8 weeks.

The expected association between visual mental imagery and affective reactivity was not found. Unexpectedly, in both previously and never depressed individuals, higher levels of imagery-based processing of mental representations in daily life were significantly associated with better momentary mood and more positive affect, regardless of valence.

The causality of effects remains to be examined in future studies.
