Can Self‐Determination Theory Explain the Self‐Perpetuation of Social Innovations? A Case Study of Slow Food at the University of Wisconsin—Madison

This case study of Slow Food at the University of Wisconsin—Madison (SFUW) examines the success of a volunteer social innovation that promotes sustainable food access. Using inductive thematic analysis of 19 in‐depth, semi‐structured interviews of past and current members, advisors, and collaborators, we find that the success of SFUW is consistent with Self‐Determination Theory. We find that among the participants, the organization satisfies the basic psychological needs for autonomy, competence, and relatedness, which in turn support intrinsic motivation. In this way, volunteering tasks become interesting, fun, and are more likely to be performed over time. The findings suggest that needs fulfillment and intrinsic motivation are linked to creating a self‐propagating social innovation where volunteers generate new ideas and successfully transfer skills to others.

Trait anxiety moderation of the effects of life stress on state anxiety

Many theories of anxiety have predicted and much previous research has indicated a person × situation interaction between stressors and trait anxiety. This study examined the hypothesized role of individual differences in trait anxiety in the relationship between naturally occurring stressors and state anxiety scores. Two hundred eighty-seven college undergraduates completed the State-Trait Anxiety Inventory, which provides both state and trait anxiety measures, and the Life Experiences Survey, which provides a measure of the amount of stress a person has undergone in the previous year. Trait anxiety scores were divided into quartiles and correlations between state anxiety scores and Life Experiences Survey scores and multiple regressions for trait anxiety and life stress to predict state anxiety were computed within each quartile. The results were that only in the first quartile was there a significant correlation between life stress and state anxiety, which was contrary to the predictions of state-trait anxiety theory. The validity of state-trait anxiety theory, as it relates to life stress, was questioned.     

Parents' reactions to finding out that their children have average or above average IQ scores

The parents of 41 children who had been given an individually-administered intelligence test were contacted approximately 19 months after testing. The sample included 20 parents who had learned their child had an Average IQ (children'smeanIQ = 100.8) and 21 parents who had learned their child had an Above Average IQ (children'smeanIQ = 130.0). Parents of Average IQ children were less accurate in their memory of test results, and they and their children experienced fewer positive consequences from IQ testing than Above Average children and their parents. Children with Above Average IQ experienced extremely low frequencies of sibling rivalry, conceit or pressure, and they and their parents experienced increased pride and/or self-confidence as a result of the IQ testing. The results as a whole suggest that parents of Average IQ children may need more psychological support during the parent informing process than parents of Above Average IQ children.     

Combined stimulus control over time allocation in response-independent schedules

Rats were exposed to concurrent schedules in which reinforcers occurred independently of behavior. In Experiment 1, rats could control time spent in the following conditions: (1) a light, (2) white noise, and (3) the absence of both light and noise. Response-independent reinforcers occurred at the same rate during the light and the noise and at either a higher rate or not at all in the absence of both stimuli. In subsequent tests, the rats spent more time in a light and noise compound than in either light or noise alone after the absence of both stimuli had signaled no reinforcers. When the absence of both stimuli had signaled a higher rate of reinforcement, however, the rats typically spent less time in the compound than in light or noise alone. In Experiment 2, rats could control time spent in the presence of a light and of a buzzer. The reinforcement rate in the light was twice that in the buzzer. In a later test, the rats spent more time in a light and buzzer compound than in the buzzer, but less time in the compound than in the light. The results show that additive summation, suppressive summation, and stimulus averaging of time allocation occur and that response rate differences between training stimuli are not necessary for these phenomena.     

The effect of a commercial game on children's block design scores on the WISC-R IQ test

Two experiments investigated the extent to which 10-year old children's scores on the WISC-R Block Design subtest were affected by prior experience with a specific commercial game that involved blocks and matching patterns. Experiment 1 found that 12 10-year old children who happened to have experience with the particular commercial game scored approximately three scaled score points higher on the WISC-R Block Design subtest than 24 matched children without game experience. In Experiment 2, 24 children who did not have prior experience with this particular commercial game were randomly assigned either to a Game condition (involving two 15-minute sessions with the game) or to a No-Game condition (which involved no further game experience). Children in the Game condition subsequently increased their WISC-R Block Design scores more than children in the No-Game condition. Taken together, the experiments indicate that relatively brief interactions with a commercial game can cause a significant improvement in children's performance on an IQ subtest.
