Concurrent variable ratio-variable interval (CONC VRVI) schedules of reinforcement, and the time-based analog of the same schedule (CONC VT*VT), have been used to determine if the matching law accounts for the distribution of choices between the behavior alternatives more accurately than the assumption that subjects distribute time between the alternatives to maximize total reinforcement rate. The results of those experiments leave room for interpretation. One problem is the lack of understanding of the theoretical outcomes associated with maximization in these schedules. A precise understanding of the characteristics of optimal behavior (OB) could help identify experimental evidence of OB. Here we derive equations that describe the optimal times the subject should spend on each alternative of the schedule. We provide a table of the optimal times for a wide range of parameter values of the schedule that experimenters can use to compare easily experimental results to the results expected if subjects behave optimally. We also derive a function m that relates matching and optimal performance and we prove interesting characteristics of the function. Finally, we describe features of OB with CONC VT*VT and with concurrent variable time schedules that can be used to identify evidence of OB. 相似文献

We investigated trait self-enhancement, explanatory variables, and adjustment in European American (n = 141), Asian American (n = 72), Mexican (n = 141), and Filipino (n = 174) college students. Consistent with trait perspectives, students in all cultural groups rated their traits with moderate to high accuracy, using peer ratings as a criterion. European Americans did not exhibit self-enhancement relative to peers, but both self and peer ratings were higher (i.e., more positive) for European Americans than for the other three groups. Support was found for some, but not all, cultural psychology explanations of self-enhancement. In all cultural groups, self-enhancement was more associated with personal (intrapsychic) adjustment than interpersonal adjustment, as judged by peers. The results provided support for an integration of trait and cultural psychology perspectives. 相似文献

Despite its status as a prominent set of theories for explaining the elicitation and differentiation of emotions, much appraisal theory and research offer little indication of the nature of the relationship expected between appraisals and emotions. Here, we present a three‐study, multiple‐method analysis in which we examine numerous ways of testing appraisal–emotion relationships using the “prosocial” intergroup emotions—sympathy, anger, and guilt—as an example. Results show that the set of appraisal dimensions that appears strongly characteristic of an emotion varies depending on the kind of appraisal—emotion relationship hypothesised and the experimental methodology/statistical analysis used. These findings demonstrate the utility of explicit theorising about the nature of the relationship between emotions and appraisals, and show how the hypothesised appraisal–emotion relationship and choice of methodology can affect the structure of appraisal theories. We recommend an analysis across multiple methods to provide a more complete picture of a given set of appraisal–emotion relationships. 相似文献

Objective: Although there is some evidence of the association between specific food groups, such as plant foods, and subjective wellbeing, this is the first study to assess the relationship between adherence to the Mediterranean dietary pattern and subjective wellbeing. Design: Data were collected in 2014–2015, within the Edad con Salud project, a follow-up study of a multistage clustered survey on a representative sample of the population of Spain. The final sample comprised 2397 individuals with ages ranging from 21 to 101 years. Main outcome measures: Experienced wellbeing (positive and negative affect) was measured using the Day Reconstruction Method, and evaluative wellbeing was assessed with the Cantril Self-Anchoring Striving Scale. Results: A higher adherence to the Mediterranean diet showed a small but statistically significant inverse relationship with negative affect (β?=??0.076, p=.001), and direct with evaluative wellbeing (β?=?0.053, p=.015), whereas it was not related to positive affect. Several components of the Mediterranean diet were independently associated with wellbeing. Conclusion: The results suggest that adherence to a dietary pattern such as the Mediterranean diet, and not only the isolated consumption of its components, is associated with a better subjective wellbeing. 相似文献

The goal of this study is to validate a Spanish version of the Physical Activity Enjoyment Scale (PACES, Kendzierski & DeCarlo, 1991), in the population of Spanish adolescent girls, and also to obtain a reduced version of the scale. For this purpose, reliability analysis was conducted, and construct validity was assessed in two steps: exploratory factor analysis and structural equation model with confirmatory factor analysis. The scale was administered to a sample of 2777 adolescent girls of Secondary Education, ages between 12-18 years. The results show the reliability of the instrument and the construct validity with a good fit of the model. The adapted scale was reduced to six items, a shorter and efficient scale that allows us to measure the enjoyment of physical activity. 相似文献

The relation between parenting styles and adolescent outcomes was analyzed in a sample of 1,198 15-18-year-old Brazilians. The adolescents were classified into 1 of 4 groups (Authoritative, Authoritarian, Indulgent, and Neglectful) on the basis of their own ratings of their parents on two dimensions: Acceptance/ Involvement and Strictness/Imposition. The adolescents were then contrasted along two different outcomes: (1) priority given to Schwartz Self-transcendence and Conservation values, and (2) level of Self-esteem (appraised in 5 domains: Academic, Social, Emotional, Family, and Physical). Results showed that Authoritative and Indulgent parenting is associated with the highest internalization of Self-Transcendence and Conservation values of teenagers, whereas Authoritarian parenting is associated with the lowest. On the other hand, adolescents with Indulgent parents have equal or higher levels of Self-esteem than adolescents with Authoritative parents, while adolescents raised in Authoritarian and Neglectful homes have the lowest scores in Self-Esteem. 相似文献

Behavior maintained with 2-component concurrent variable interval schedules of reinforcement (CONC VIVI) is described well by the matching law. Deviations from matching behavior have been handled by adding free parameters to the matching law equation. With CONC VIVI schedules there are infinitely many solutions to the matching law equation at each value of the procedural parameters. However, at each value of the procedural parameters, only one combination of durations of intervals spent in each VI component (dwell times) yields the combined maximum reinforcement rate. The equations that yield the optimal dwell times solution for CONC VIVI schedules are mathematically incompatible with the matching law. Optimal performance and matching coincide only when the parameter values of the two VI components are equal. It seems reasonable to use optimal behavior to assess performance in these schedules. Researchers have not compared optimal and empirical performances in CONC VIVI possibly because the equations for optimal dwell times (ODT) can be solved only numerically. We present a table of ODT for a wide range of VIs and changeover delays. We also derive a function m that can be used to compare matching data and the matching behavior predictions of optimization. We prove that 0.5<m<1.003502, and we describe some of the more nteresting properties of the function. 相似文献

We look at two fundamental logical processes, often intertwined in planning and problem solving: inference and update. Inference
is an internal process with which we uncover what is implicit in the information we already have. Update, on the other hand,
is produced by external communication, usually in the form of announcements and in general in the form of observations, giving
us information that might not have been available (even implicitly) before. Both processes have received attention from the
logic community, usually separately. In this work, we develop a logical language that allows us to describe them together.
We present syntax, semantics and a complete axiom system; we discuss similarities and differences with other approaches and
mention how the work can be extended. 相似文献

We present new Spanish norms for object familiarity and rated age of acquisition for 140 pictures taken from Snodgrass and Vanderwart (1980), together with data on visual complexity, image agreement, name agreement, word length (in syllables and phonemes), and five measures of word frequency. The pictures were presented to a group of 64 Spanish subjects, and oral naming latencies were recorded. In a multiple regression analysis, age of acquisition, object familiarity, name agreement, word frequency, and word length made significant independent contributions to predicting naming latency. 相似文献

We experimentally approach the discursive dilemma to gain insight into people's procedural appropriateness judgments. We relied on a vignette in which three people had formed opinions about two skills (premises) of a candidate to decide whether to hire her/him (conclusion). The dilemma arises when different outcomes (hire vs. not hire) are achieved depending on whether the majority opinion is independently considered for each premise or for the global conclusion of each judge. Participants were asked to choose the procedure they thought to be more appropriate to reach a decision. In Experiment 1, we found a leniency effect (a bias to prefer the aggregation procedure that led to hiring the candidate), which was reduced by introducing the participant as a juror with an exogenously provided negative opinion about the candidate's skills. In Experiment 2, we replicated the opinion effect, even when subjects did not participate as jury members. In Experiment 3, we found that the leniency bias was only reduced when participants' negative opinion was aligned with a majority of negative premises, but not with a majority of negative conclusions. We discuss present findings in terms of the identification of empirical regularities that may affect people's procedural legitimacy judgments. 相似文献
