Perceived partner support and psychosexual adjustment to breast cancer

Support from a partner can play a key role in a woman's emotional adjustment to breast cancer. However, little is known about the influence of partner behaviours on a woman's sexual adjustment. This study examined the prospective relationship between baseline levels of several types of perceived partner support (instrumental, informational, emotional and negative) and psychosexual adjustment (sexual functioning and relationship satisfaction) over the course of 12 months post-surgery in a sample of 130 women with breast cancer. Results indicated that perceptions of greater emotional and informational support from the partner at baseline were associated with less sexual difficulties among breast cancer patients concurrently and 6 months post-surgery. Baseline perceptions of greater emotional and instrumental support from a partner were associated with greater relationship satisfaction at all time points. Perceptions of informational support at baseline were related to greater concurrent relationship satisfaction. Baseline perceptions of negative partner support were related to less relationship satisfaction, but only concurrently. These findings suggest that the perception of a partner's provision of emotional, instrumental and informational support may each play a role in facilitating sexual adjustment and relationship satisfaction.     

The ease-of-processing heuristic and the stability bias: dissociating memory, memory beliefs, and memory judgments

Judgments about memory are essential in promoting knowledge; they help identify trustworthy memories and predict what information will be retained in the future. In the three experiments reported here, we investigated the mechanisms underlying predictions about memory. In Experiments 1 and 2, single words were presented once or multiple times, in large or small type. There was a double dissociation between actual memory and predicted memory: Type size affected predicted but not actual memory, and future study opportunities affected actual memory but scarcely affected predicted memory. The results of Experiment 3 suggest that beliefs and judgments are largely independent, and neither consistently resembles actual memory. Participants' underestimation of future learning-a stability bias-stemmed from an overreliance on their current memory state in making predictions about future memory states. The overreliance on type size highlights the fundamental importance of the ease-of-processing heuristic: Information that is easy to process is judged to have been learned well.

Individuals and environments: Linking ability and skill ratings with interests

Holland's (1997) theory of corresponding person and work environment structures was evaluated by comparing the integration of individual and occupational ratings of interests, abilities, and skills. Occupational ratings were obtained from the U.S. Department of Labor's O*NET database (U.S. Department of Labor, 2007). College students (494 women, 526 men) provided self-ratings of their interests, abilities, and skills. Property vector fitting was used to embed ability and skill ratings into the Realistic, Investigative, Artistic, Social, Enterprising, and Conventional (RIASEC) interest structure, and bootstrapping was used to generate confidence intervals for the angles of the vectors and the magnitude of their fit to the Holland model. Across the individual and occupational ratings, 18 of 45 (40%) ability vectors and 41 of 48 (85%) skill vectors were fit into the RIASEC model. No significant gender differences were found in the integration of self-rated abilities and skills into the RIASEC circumplex; however, some differences were found between individual and environmental ratings. Obtained results highlight the potential utility and limitations of using Holland's model for representing both individual and occupational data in a common structure.     

The apes’ edge: positional learning in chimpanzees and humans

A wide variety of organisms produce actions and signals in particular temporal sequences, including the motor actions recruited during tool-mediated foraging, the arrangement of notes in the songs of birds, whales and gibbons, and the patterning of words in human speech. To accurately reproduce such events, the elements that comprise such sequences must be memorized. Both memory and artificial language learning studies have revealed at least two mechanisms for memorizing sequences, one tracking co-occurrence statistics among items in sequences (i.e., transitional probabilities) and the other one tracking the positions of items in sequences, in particular those of items in sequence-edges. The latter mechanism seems to dominate the encoding of sequences after limited exposure, and to be recruited by a wide array of grammatical phenomena. To assess whether humans differ from other species in their reliance on one mechanism over the other after limited exposure, we presented chimpanzees (Pan troglodytes) and human adults with brief exposure to six items, auditory sequences. Each sequence consisted of three distinct sound types (X, A, B), arranged according to two simple temporal rules: the A item always preceded the B item, and the sequence-edges were always occupied by the X item. In line with previous results with human adults, both species primarily encoded positional information from the sequences; that is, they kept track of the items that occurred in the sequence-edges. In contrast, the sensitivity to co-occurrence statistics was much weaker. Our results suggest that a mechanism to spontaneously encode positional information from sequences is present in both chimpanzees and humans and may represent the default in the absence of training and with brief exposure. As many grammatical regularities exhibit properties of this mechanism, it may be recruited by language and constrain the form that certain grammatical regularities take.
