The Racial Digital Divide: Motivational,Affective, and Cognitive Correlates of Internet Use1

The indisputable existence of a racial digital divide calls into question the democratizing potential of the Internet. Beyond issues of access to the technology are psychological factors that may influence Internet use. A survey of 787 college undergraduates—630 European Americans and 157 African Americans—who have similar access to the Internet was used to examine motivational, affective, and cognitive factors that may influence Internet use and contribute to the racial digital divide. Racial differences in Internet use were obtained, but were limited to e‐mail use. A model of Internet use is offered that considers motivational, affective, and cognitive antecedents and consequences of use.     

Teaching oddity and insertion to Head Start children: An economical cognitive intervention

Two interventions were offered to Head Start preschoolers. Half of the children played numerous learning set games designed to teach the children (1) the oddity principle and (2) how to insert objects into a series. Mastery of these concepts is theoretically an important aspect of school readiness. The other half of the children engaged in the I Can Problem Solve (ICPS) exercises, a program designed to increase the children's competency in recognizing and responding to other people's feelings. The children who played the learning set games became superior at oddity and insertions with manipulable objects, and generalized these games to workbook-like formats resembling those encountered in kindergarten. They also scored higher on the numeracy and memory scales of the McCarthy Scales of Children's Abilities, indicating that mastery of oddity and insertions may have served as foundations for further cognitive growth. The children who participated in the ICPS exercises became superior at creating solutions to interpersonal problems, as measured by the Preschoolers Interpersonal Problem Solving Scale. The differences in the outcomes indicate that both interventions were successful in their own domains. The advantage the cognitive intervention produced on the McCarthy Scales suggests that oddity and insertion abilities may be a foundation in fact as well as in theory for general cognitive growth at this age.     

Optimism and Traumatic Stress: The Importance of Social Support and Coping1

This study examined the effects of optimism following traumatic stress and pathways through which optimism may act. Rescue and recovery workers at the crash site of US Air Flight 427 (n= 159) were studied 2, 6, 9, and 12 months after the crash to examine optimistic outlook, social support, coping, and stress. As predicted, a more optimistic disposition was associated with less self‐reported distress, less use of avoidant and wishful‐thinking coping strategies, greater use of problem‐focused and seeking‐social‐support coping, and greater availability of social support. Contrary to expectations, coping did not account for the relationships observed between optimism and stress responding. Social support explained some of the effects of optimism on coping and stress, but these mediational effects varied over time. Findings suggest that optimism affects stress and coping directly and indirectly by affecting how much social support is available.     

A model career assistance process for individuals with severe disabilities

This article describes a model process for providing career services to individuals with severe disabilities and presents the outcomes of a 3‐year demonstration project. After completing a career workshop series based at a community college followed by job search support and ongoing follow‐up with employers and employees, all 40 project participants achieved paid employment, with 74.4% employed midway through Year 3. Jobs represented a wide range of occupational areas, and most jobs paid over the minimum wage and included benefits. Implications for enhancing career services and outcomes for this population are discussed.     

Cache protection strategies of a non-social food-caching corvid,Clark’s nutcracker (<Emphasis Type="Italic">Nucifraga</Emphasis><Emphasis Type="Italic">columbiana</Emphasis>)

Clark’s nutcrackers (Nucifraga columbiana), a non-social corvid, cache much of their food in order to survive periods of resource uncertainty. These caches are at risk as they are subject to pilferage from other animals including conspecifics. Potentially, nutcrackers can ensure the safety of these caches by keeping track of whether they have been observed making a cache and subsequently engage in cache protection strategies—strategies that have been shown by other members of the corvid family (e.g., scrub-jays and ravens). Behaviors including creating more caches, eating a higher proportion of seeds, and re-caching existing compromised sites have been shown in laboratory settings with social corvids and have provided preliminary evidence of the complex cognitive abilities of corvids. In the present study, Clark’s nutcrackers are shown to engage in similar cache protection behaviors when observed by a conspecific. Furthermore, we show that these behaviors are a result of social, rather than associative, cues.     

Emotional state affects the initiation of forward gait

The aim of the current study was to determine the extent to which pleasant and unpleasant emotional states impact the initiation of forward gait. Participants initiated gait and walked for several steps following the presentation of low arousing pleasant, high arousing pleasant, low arousing unpleasant, high arousing unpleasant, and neutral pictures. Reaction time, displacement, and velocity of the center of pressure (COP) trajectory, and length and velocity of the first and second steps were calculated. Exposure to the highly arousing unpleasant pictures reduced reaction times compared to all other affective conditions. Compared to the low arousing unpleasant pictures, exposure to the high and low arousing pleasant pictures increased the displacement of the COP movement during the anticipatory postural adjustment phase of gait initiation. Additionally, exposure to the low arousing pleasant pictures increased the velocity of the COP movement during the anticipatory postural adjustment phase, compared to the high and low arousing unpleasant pictures. Exposure to the high and low arousing pleasant pictures increased the velocity of the first step relative to the low arousing unpleasant pictures. These findings demonstrate that highly arousing unpleasant emotional states accelerate the initial motor response, but pleasant emotional states generally facilitate the initiation of forward gait due to the approach-oriented directional salience of the movement. These findings extend the scope of the motivational direction hypothesis by demonstrating the effects of emotional reactivity on the initiation of gait.     

Physical cues of ovulatory status: A failure to replicate enhanced facial attractiveness and reduced waist-to-hip ratio at high fertility

We investigated women's facial attractiveness and body shape as a function of menstrual cycle phase, with the expectation from previous research that both would be enhanced during the high fertile phase. To control for the effects of women's daily behaviors on their appearance and waistline, we visited 37 normally cycling women twice in their dorm, where we photographed and measured them at low and high fertile days of their cycle immediately upon their waking. Seventy-four judges from a separate institution chose, for each woman, the picture they thought was more attractive. We analyzed a subset of 20 women who, by forward counting, had a High Fertility visit between Days 10-13 and a Low Fertility visit between Days 20-23; and we also analyzed a subsample of 17 women who, by reverse counting, had a High Fertility visit on the days leading to ovulation and a Low Fertility visit one week after ovulation. In neither set of analyses were women's waist- to-hip ratios lower nearer ovulation, and in neither set were women's high fertile pictures chosen at an above-chance rate by either male or female judges. We did not find evidence that facial attractiveness and waist-to-hip ratio are reliable physical cues of ovulatory status.     

The developing role of prosody in novel word interpretation

This study examined whether children use prosodic correlates to word meaning when interpreting novel words. For example, do children infer that a word spoken in a deep, slow, loud voice refers to something larger than a word spoken in a high, fast, quiet voice? Participants were 4- and 5-year-olds who viewed picture pairs that varied along a single dimension (e.g., big vs. small flower) and heard a recorded voice asking them, for example, “Can you get the blicket one?” spoken with either meaningful or neutral prosody. The 4-year-olds failed to map prosodic cues to their corresponding meaning, whereas the 5-year-olds succeeded (Experiment 1). However, 4-year-olds successfully mapped prosodic cues to word meaning following a training phase that reinforced children’s attention to prosodic information (Experiment 2). These studies constitute the first empirical demonstration that young children are able to use prosody-to-meaning correlates as a cue to novel word interpretation.
