Appearance questions can be misleading: a discourse-based account of the appearance-reality problem

Preschoolers' success on the appearance-reality task is a milestone in theory-of-mind development. On the standard task children see a deceptive object, such as a sponge that looks like a rock, and are asked, "What is this really?" and "What does this look like?" Children below 412 years of age fail saying that the object not only is a sponge but also looks like a sponge. We propose that young children's difficulty stems from ambiguity in the meaning of "looks like." This locution can refer to outward appearance ("Peter looks like Paul") but in fact often refers to likely reality ("That looks like Jim"). We propose that "looks like" is taken to refer to likely reality unless the reality is already part of the common ground of the conversation. Because this joint knowledge is unclear to young children on the appearance-reality task, they mistakenly think the appearance question is about likely reality. Study 1 analyzed everyday conversations from the CHILDES database and documented that 2 and 3-year-olds are familiar with these two different uses of the locution. To disambiguate the meaning of "looks like," Study 2 clarified that reality was shared knowledge as part of the appearance question, e.g., "What does the sponge look like?" Study 3 used a non-linguistic measure to emphasize the shared knowledge of the reality in the appearance question. Study 4 asked children on their own to articulate the contrast between appearance and reality. At 91%, 85%, and 81% correct responses, children were at near ceiling levels in each of our manipulations while they failed the standard versions of the tasks. Moreover, we show how this discourse-based explanation accounts for findings in the literature. Thus children master the appearance-reality distinction by the age of 3 but the standard task masks this understanding because of the discourse structure involved in talking about appearances.     

Roll-over characteristics of human walking on inclined surfaces

Roll-over characteristics of able-bodied human subjects walking on ramped surfaces were examined in this study. Ten subjects walked at their normal self-selected speed on a level surface, a 5-deg ramp, and a 10-deg ramped surface. Ramps were designed such that ground reaction forces and center of pressure of the ground reaction forces could be measured on their surfaces. This set-up facilitated calculation of the effective rockers that the ankle-foot (AF) and knee-ankle-foot (KAF) systems conformed to during single-limb stance (contralateral toe off to contralateral heel contact). Since our original "roll-over shapes" were characterized between heel contact and opposite heel contact, we label the shapes found during single-limb stance as "truncated roll-over shapes". We hypothesized that the ankle-foot system would adapt to the various surfaces, creating a roll-over shape that would change in orientation with different levels of inclination. The truncated AF roll-over shapes supported this hypothesis for uphill walking but did not support the hypothesis for downhill walking. However, truncated roll-over shapes of the KAF system did adjust their orientation to match both the positive and negative levels of surface inclination. In general, the ankle appears to be the main adapting joint when walking up inclined surfaces while the knee becomes important for the overall adaptation in downhill walking. Knowledge of physiological lower-limb roll-over characteristics on ramped surfaces may help in the development of biomimetic prostheses and orthoses that will automatically adapt to changes in walking surface inclination.     

Use of the mutual exclusivity assumption by young word learners

A critical question about early word learning is whether word learning constraints such as mutual exclusivity exist and foster early language acquisition. It is well established that children will map a novel label to a novel rather than a familiar object. Evidence for the role of mutual exclusivity in such indirect word learning has been questioned because: (1) it comes mostly from 2 and 3-year-olds and (2) the findings might be accounted for, not by children avoiding second labels, but by the novel object which creates a lexical gap children are motivated to fill. Three studies addressed these concerns by having only a familiar object visible. Fifteen to seventeen and 18-20-month-olds were selected to straddle the vocabulary spurt. In Study 1, babies saw a familiar object and an opaque bucket as a location to search. Study 2 handed babies the familiar object to play with. Study 3 eliminated an obvious location to search. On the whole, babies at both ages resisted second labels for objects and, with some qualifications, tended to search for a better referent for the novel label. Thus mutual exclusivity is in place before the onset of the naming explosion. The findings demonstrate that lexical constraints enable babies to learn words even under non-optimal conditions--when speakers are not clear and referents are not visible. The results are discussed in relation to an alternative social-pragmatic account.     

Navigating the nuances: a matrix of considerations for ethical-legal dilemmas

At one time or another, we all have encountered cases with serious ethical and legal implications. How can we know that we have thoroughly explored every facet of these dilemmas? The authors present a 7-category matrix of the following considerations: moral principles and personal values, clinical and cultural considerations, ethics codes, agency or employer policies, statues, rules and regulations, and case law. Two clinical examples illustrate the usefulness of this multidimensional framework for professional psychologists. Implications and applications for practitioners and ethics educators are also discussed.     

Reductions in criminality subsequent to group, individual, and family therapy in adolescent residential and day treatment settings.

The complete population of adolescents in a residential and day-treatment program over a 4-year period, 532 youths, served in two studies. Along with residential and day-treatment settings, predictive variables of interest were the number of hours spent in group, individual, and family therapy. A total of 227 adolescents qualified for Study 1 which found a reduction of rates of criminal charges from pre- to posttreatment. Study 1 also found that hours in group therapy explained the most variance in the reduction in rates of criminal charges, followed closely by hours in individual therapy. Hours in family therapy was not a significant predictor. A total of 430 adolescents qualified for Study 2, which found that residential treatment was associated with greater reductions in adult correctional commitments than day treatment. Implications stress the need for further research examining the relationships between therapeutic components of residential treatment and behavioral outcomes.     

Deterring the Onset of Smoking in Children: Knowledge of Immediate Physiological Effects and Coping with Peer Pressure,Media Pressure,and Parent Modeling1

Entering seventh grade, most children believe that smoking endangers their long-term health. Nevertheless, three sources of social pressure were found to often have an overriding influence to begin smoking: peers, models of smoking parents, and media. Interventions were developed to train children to cope with these pressures. Also stressed were immediate rather than long-term physiological effects of smoking. A dependent measure was utilized that generates increased validity of self-reports of smoking. A 10-week investigation was completed with 750 male and female students entering the seventh grade. Rates of onset of smoking in treatment groups were significantly lower than in a pretest-single posttest control group.     

Feminine role concepts of young women

A summary of three studies of feminine role concepts is reported. Different samples were used in each study. The findings indicate: (1). Housewives had a discrepancy between their own and their ideal feminine role while graduate students and club women expressed no significant differences. All three groups expressed differences between their own feminine role and their concept of man's ideal feminine role. (2). High school girls and their mothers showed no significant differences between their own and their ideal feminine role concepts. (3). The high school girls with more traditional feminine role self-concepts were significantly less verbal in the classroom.     

Four seasons in femininity orfour men in a woman's life

Conclusion The feminine complaint that Alex's passion echoes, raising it to a level rarely attained, is not limited to the pursuit of sexualjouissance. Nor can it be reduced to an aversion on the part of women to a morality of the signifier, as maintained by a certain reading of Freud. Very precisely, the persistent note in feminine restlessness is a certain relationship of the subject to the insufficiency of the signifier, which the quest for love registers. The fact that language lacks the very quality that would make it credible and that would guarantee that discourse corresponds to what desire attests to is what delivers femininity over to the unnameable. In love she requires from the other member of the social bond the signifier that is lacking within the structure of femininity and that causes the call tojouissance in her body that drives her to distraction. Thus, the structure at stake in femininity, to which Alex's hysterical passion bears witness, defines in writing, that is, by a mark left on the body, the limitation of the reality of ajouissance which persists beyond the signifier and the object of the fantasy. When the analyst's desire offers support to this quest for a limit tojouissance on the part of a subject, it is in desire that the reality of sex and the other is linked to the signifier that would testify to the truth of the amorous discourse in the unconscious. Thus from one man to another, from the love of the father to the loss of a son, including the desire of the lover and the law of the husband, a woman finds herself supporting, with the letter of her body, the signifier which in its words testifies tojouissance as a place to lose oneself.     

Instrumental Behaviors Following Test Administration and Interpretation: Exploration Validity of the Strong Interest Inventory

A two-phase longitudinal study was conducted to explore the exploration validity (i.e., the power of interest inventories to facilitate career exploration activities such as talking to professionals and seeking vocational information) of the 1985 Strong Interest Inventory (SII) for college students. Participants in the study included an experimental group (N =75), which participated in the SII testing and a group interpretation, and a contrast group(N=67). Students in the experimental group reported significantly more instrumental career exploration behaviors at a 1-year follow-up than did the contrast group.
