Permanent genetic resources added to Molecular Ecology Resources Database 1 October 2011-30 November 2011.

This article documents the addition of 139 microsatellite marker loci and 90 pairs of single-nucleotide polymorphism sequencing primers to the Molecular Ecology Resources Database. Loci were developed for the following species: Aglaoctenus lagotis, Costus pulverulentus, Costus scaber, Culex pipiens, Dascyllus marginatus, Lupinus nanus Benth, Phloeomyzus passerini, Podarcis muralis, Rhododendron rubropilosum Hayata var. taiwanalpinum and Zoarces viviparus.

A comparison of the effects of thought suppression, distraction and concentration.

This study compared the effects of suppression, focused-distraction, and concentration on controlling unwanted distressing thoughts, and examined how anxiety levels were associated with the use of each thought-control technique. In the study, college students were told to suppress thoughts about a distressing story, to suppress the same thoughts by focusing on an alternative distraction task, to simply concentrate on that alternative task, or to think about anything without restrictions for 6minutes. This initial period was followed by a "free-thinking" period to assess the delayed effect of thought-control techniques.

Goal orientation, goal difficulty, and incentive values of academic goals.

We examined relationships among goal attributes (difficulty and affective value) and goal types (mastery, performance, intrinsic, and extrinsic). Goal attributes of positive affect value and relative salience of positive value were higher for intrinsic goals, mastery goals, and more difficult goals, qualified by an interaction between difficulty and type of goal. Intrinsic goals were more affectively positive than extrinsic goals and mastery goals were more positive than performance goals, but these differences vanished if goals were also perceived as difficult.

Motivation when optimism declines: data on temporal dynamics.

To contribute to a description of motivation variables across time, the authors examined temporal changes in these variables as the time to pursue a test-taking goal approached. In three samples, expected performance, grade-level standards, and perceived adequacy of effort decreased as the test time approached, but other indices of motivation did not always decrease. Data indicated that (a) there is a strong relationship between expectancies and implicit goal setting, (b) students may sometimes change goal levels and definitions of success to maintain their desire for chosen goals despite declining expectations, (c) effects of event proximity on goal-achievement expectations may be based on overestimating the adequacy of future effort, and (d) the degree to which expectancy and value predict motivation appears to vary with exam proximity.

From wishing to intending: differences in salience of positive versus negative consequences.

Goal ratings by 345 subjects in seven data samples supported a functional distinction between two types of positive incentive value, one based on approaching positive affect (positive-based value or PBV), the other on avoiding negative affect (negative-based value or NBV). Ratings of PBV were more related to ratings of earlier action-phases of motivation ("wishing"), whereas ratings of NBV tended to be more related to factors entailed in later action-phases ("urgency/priority" and "intention"). These findings and previous ones are consistent with the proposal that this distinction parallels distinctions in Maslow's motivation theory.
