Development of conditional and equivalence relations without differential consequences

Two experiments were conducted to establish conditional stimulus relations without differential consequences and to test for the emergence of other relations. In Experiment 1, 3 adults responded to match-to-sample displays in which sample-comparison pairs were constant while the second comparison presented with each pair changed periodically across trials. No differential consequences followed any comparison selections. All subjects learned conditional relations between constant samples and comparisons, but results of tests for transitivity in those relations were equivocal. In Experiment 2, 4 children were given unreinforced training and testing similar to that provided to the adults in Experiment 1, with procedural refinements. One child learned conditional relations and demonstrated emergent relations that confirmed the development of two four-member equivalence classes. Another child learned the conditional relations but did not demonstrate any emergent relations reliably. A 3rd child, after reinforced training on two conditional relations, learned four new conditional relations without differential consequences and demonstrated symmetry but not equivalence in the trained relations. The 4th child did not learn the conditional relations. These findings emphasize the importance of careful construction of tests for stimulus equivalence and suggest a need for critical analyses of the apparent emergence of untrained stimulus relations on unreinforced tests that has been observed in several stimulus equivalence studies.     

Qualities, Relations, and Property Exemplification

The question whether qualities are metaphysically more fundamental than or mere limiting cases of relations can be addressed in an applied symbolic logic. There exists a logical equivalence between qualitative and relational predications, in which qualities are represented as one-argument-place property predicates, and relations as more-than-one-argument-place predicates. An interpretation is first considered, according to which the logical equivalence of qualitative and relational predications logically permits us ontically to eliminate qualities in favor of relations, or relations in favor of qualities. If metaphysics is understood at least in part as an exercise in ontic economy, then we may be encouraged to adopt a property ontology of qualities without quality-irreducible relations, or relations without relation-irreducible qualities. If either strategy is followed, the choice of reducing qualities to relations or relations to qualities will need to be justified on extra-logical grounds. These might include a perceived greater intuitiveness, explanatory fecundity, compatibility with cognitive ontogeny or developmental psychology, expressive or explanatory elegance or cumbersomeness, and an open-ended list of philosophical motivations that could reasonably favor the ontic prioritization of qualities over relations or relations over qualities. Despite its intuitive appeal, the thesis that logical equivalence together with extra-logical preferences justifies unidirectional ontic reduction of relations to qualities or qualities to relations is rejected in light of the more defensible proposition that the logical equivalence of qualitative and relational predications actually supports the opposite conclusion, that both qualities and relations are logically indispensable to a complete ontology of properties. The logical equivalence of qualitative and relational predications, insofar as we continue to observe the distinction, makes it logically necessary ontically for both qualities and relations to exist whenever either one exists. That logically equivalent qualitative and relational predications have as their truth-makers the exemplification by objects of both qualities and relations as equi-foundational properties further suggests that there is no deeper logical distinction between qualities and relations, but only two convenient lexical-grammatical designations for property predications involving one- versus more-than-one-argument-place.     

The similarity and diversity of semantic relations

There is a rich variety of semantic relations in natural languages. Subjects’ perceptions of similarities among relations were studied for a wider variety of relations than had been used in previous studies. Forty subjects sorted 31 cards bearing five example pairs of each of 31 semantic relations. Subjects were able both to distinguish the relations and to perceive their similarities. A hierarchical clustering analysis of the sorting data indicated that the subjects perceived five families of semantic relations (contrasts, class inclusion, similars, case relations, and part-wholes). The five families were distinguished in terms of three properties of semantic relations: contrasting/noncontrasting, logical/pragmatic, and inclusion/noninclusion. Within each family, relations also were sorted in ways consistent with their defining properties. Relations were therefore viewed not as unanalyzable primitives, but in terms of the relational properties that distinguished them.     

Producing and Recognizing Analogical Relations

Analogical reasoning is an important component of intelligent behavior, and a key test of any approach to human language and cognition. Only a limited amount of empirical work has been conducted from a behavior analytic point of view, most of that within Relational Frame Theory (RFT), which views analogy as a matter of deriving relations among relations. The present series of four studies expands previous work by exploring the applicability of this model of analogy to topography-based rather than merely selection-based responses and by extending the work into additional relations, including nonsymmetrical ones. In each of the four studies participants pretrained in contextual control over nonarbitrary stimulus relations of sameness and opposition, or of sameness, smaller than, and larger than, learned arbitrary stimulus relations in the presence of these relational cues and derived analogies involving directly trained relations and derived relations of mutual and combinatorial entailment, measured using a variety of productive and selection-based measures. In Experiment 1 participants successfully recognized analogies among stimulus networks containing same and opposite relations; in Experiment 2 analogy was successfully used to extend derived relations to pairs of novel stimuli; in Experiment 3 the procedure used in Experiment 1 was extended to nonsymmetrical comparative relations; in Experiment 4 the procedure used in Experiment 2 was extended to nonsymmetrical comparative relations. Although not every participant showed the effects predicted, overall the procedures occasioned relational responses consistent with an RFT account that have not yet been demonstrated in a behavior-analytic laboratory setting, including productive responding on the basis of analogies.     

The organisation of spatial and temporal relations in memory

Episodic memories are comprised of details of “where” and “when”; spatial and temporal relations, respectively. However, evidence from behavioural, neuropsychological, and neuroimaging studies has provided mixed interpretations about how memories for spatial and temporal relations are organised—they may be hierarchical, fully interactive, or independent. In the current study, we examined the interaction of memory for spatial and temporal relations. Using explicit reports and eye-tracking, we assessed younger and older adults’ memory for spatial and temporal relations of objects that were presented singly across time in unique spatial locations. Explicit change detection of spatial relations was affected by a change in temporal relations, but explicit change detection of temporal relations was not affected by a change in spatial relations. Younger and older adults showed eye movement evidence of incidental memory for temporal relations, but only younger adults showed eye movement evidence of incidental memory for spatial relations. Together, these findings point towards a hierarchical organisation of relational memory. The implications of these findings are discussed in the context of the neural mechanisms that may support such a hierarchical organisation of memory.     

Functionality and spatial relations in memory and language

We examined whether the functionality of spatial relations affects the construction and memory of information in situation models. A functional relationship involves the interaction of entities that is implied by either typical use or contextual demands. Previous research has shown that spatial relations are less likely to be encoded during comprehension unless there is extensive prior knowledge, explicit instructions to attend to spatial information, or a clear emphasis on spatial information. If the construction of a situation model is guided by a need to understand the functional structure of a situation, then functional spatial relations should be more likely to be encoded. The results of our study showed that sentences with functional spatial relations were read faster and remembered better in both recall and recognition tests than sentences with nonfunctional spatial relations.     

Post-divorce mother-son relations of delinquent and well-adjusted adolescents

This study exmined the long-term effects of divorce an adolescent boy's relations with their mothers. Eighteen ealry father-absent (before age 5), 18 late father-absent (between ages 5 and 10), and 18 infant families with a delinqunet or a well-adjusted male adolscent were evaluated using observational and self-report measures of mother-son relations, as well as personality measures. Multivariate between-groups comparisons indicated that the relations of divorced mothers and their sons were more conflictive and less warm than were mother-son relations in infant families. Moreover, mother-son relations were least positive ie early father-absent families. Regarless of the intactness of the home, fammilies with a delinquent boy evidenced difficulties in several areas of mother-adolescent relations. These findings suggest that the task of raising an adolescent son in generally more difficult in divorced than in intact families, but that the association between adolescent behavioral maladjustment and mother-adolescent relations is similar across family structures.     

Semantic categorical flexibility and aging: effect of semantic relations on maintenance and switching

The authors studied the effects of aging on the flexible use of categorization rules based on thematic and taxonomic relations. Two components of flexibility were distinguished: maintenance of a categorical relation, and switching between two relations. Results showed that age affects these two components. In older adults, an effect of the nature of the categorical relations to be used was revealed. Older adults demonstrated a specific difficulty in the flexible use of taxonomic relations. Moreover, all adults, independent of their age, showed better performance in maintaining the use of a categorical relation than in switching between two categorical relations.     

Melting chocolate and melting snowmen: analogical reasoning and causal relations

Children's performance in the classical a:b::c:d analogy task is traditionally very poor prior to the Piagetian stage of formal operations. The interpretation has been that the ability to reason about higher-order relations (the relations between the a:b and c:d parts of the analogy) is late-developing. However, an alternative possibility is that the relations used to date in the analogies are too difficult for younger children. Two experiments presented children aged 3, 4 and 6 years with a:b::c:d analogies which were based on relations of physical causality such as melting and cutting, for example chocolate bar:melted chocolate::snowman:melted snowman. Understanding of these particular causal relations is known to develop between the ages of 3 and 4 years. It was found that even 3-year-olds could solve the classical analogies if they understood the causal relations on which they were based.     

Understanding intuition and how the mind works

The associations between maternal reports of positive marital quality (i.e., positive emotional expressions, constructive conflict, and mothers’ marital satisfaction) and 3–6-year-olds’ (N = 62) positive peer relations were examined as a function of child temperament and gender. Although a zero-order correlation indicated that marital quality was unrelated to peer relations, a regression analysis indicated that high levels of positive marital quality were associated with more positive peer relations for preschoolers low in effortful control, but not for those high in effortful control. In addition, a moderating effect of gender revealed that the relationship between marital quality and positive peer relations was positive for girls but negative for boys. However, positive emotionality did not moderate the relations among marital quality and peer relations. The present study provides important preliminary findings that highlight the need for further study of the significance of positive marital relations for child development.     

Demanding kin relations and depressive symptoms among low-income African American women: mediating effects of self-esteem and optimism

Association of demanding kin relations, depressive symptoms, self-esteem, and optimism was assessed among 130 low-income African American women. Demanding relations with kin were positively associated with depressive symptoms and negatively linked to self-esteem and optimism. Self-esteem and optimism were negatively associated with depressive symptoms and mediated the association of demanding relations with kin and women's depressive symptoms. Findings were discussed in terms of the detrimental effects of demanding social relations with kin and the possible role that other relationships may play in compensating for poor relations with extended family.     

Sociology, social structure and health-related stigma

There is a long and cross-disciplinary tradition of analysing chronic and disabling illness in terms of relations of stigma. The present paper offers a sociological approach which emphasizes: (a) the causal importance of social structures for grasping stigma relations; (b) the importance of understanding stigma relations in the context of wider societal change; and (c) the ways in which relations of stigma typically interact with other relations, such as those of class and command. It is suggested that consideration of specific and often condition-related strategies to reduce stigma might profitably be set in such a context.     

Demanding Kin Relations,Adjustment Problems and Academic Achievement and Engagement among Low-Income,African American Adolescents

The investigation was an exploratory study that examined the association of externalizing and internalizing problems with school achievement and school engagement in a sample of African American mothers and adolescents (N?=?200). The study also assessed whether demanding kin relations moderated the relations between these variables. Hypotheses were examined with structured interviews administered to mothers and adolescents. Results revealed that externalizing problems were negatively associated with adolescents’ school achievement. Also, the negative relations of externalizing problems with school achievement and school engagement were especially apparent in families with demanding kin relations. Additional research is needed on potential antecedents of demanding kin relations as well as the processes mediating the effects of negative relations with kin.     

Emergence of relations and the essence of learning: a review of Sidman's Equivalence relations and behavior: a research story. Book review

The author reviews and comments on the book Equivalence relations and behavior: a research story by Murray Sidman. Sidman's book reports his research about equivalence relations and competencies in children with mental retardation and how it relates to behavior. Sidman used the idea of stimulus-stimulus relations among features of the environment to develop his theories about equivalence relations. Experimental work with children and animals demonstrated their ability to use equivalence relations to learn new tasks. The subject received feedback and reinforcement for specific choices made during training, then was presented with new choices during testing. Results of the tests indicate that subjects were able to establish relations and retrieve them in different situations.     

Parenting Practices and Adolescent Internalizing and Externalizing Problems: Moderating Effects of Socially Demanding Kin Relations

Association of socially demanding kin relations, mother’s emotional support, behavioral control/monitoring, family organization and psychological control with adolescent’s internalizing and externalizing problems were assessed in 200 economically disadvantaged, African American mothers and adolescents. Demanding kin relations and mother’s psychological control were positively associated with adolescent’s internalizing problems. Demanding kin relations also moderated the association of control/monitoring, family organization, and psychological control, with internalizing. For mothers with more demanding kin relations, increased control/monitoring was associated with increased adolescent internalizing. In comparison, increased control/monitoring was associated with decreased adolescent internalizing for mothers with less demanding kin relations. Negative association of family organization with internalizing was more apparent for mothers with more compared to less demanding kin relations. Positive association of mother’s psychological control with internalizing was more apparent for mothers with more compared to less socially demanding kin relations. Demanding kin relations and mother’s psychological control were positively associated with adolescent’s externalizing problems. Mother’s emotional support and family organization were negatively associated with externalizing. Also, negative association of family organization with externalizing was more apparent for families with more compared to less demanding kin relations. The need for research on the factors associated with negative relation with kin was discussed.     

Contributions of object relations theory and self psychology to relational psychology and group psychotherapy

Object relations theory and self psychology are psychoanalytic perspectives that are especially concerned with interpersonal relations and their mental representations. Object relations theory began as an intrapsychic "singleton" psychology with the work of Freud and Melanie Klein. It subsequently evolved into a multi-person psychology with the work of Bion on groups, as well as the clinical and theoretical contributions of Winnicott and Fairbairn. Kohutian self psychology, which emerged later, has been interested in the relations between the self and significant others as mirroring and idealizing "self-objects." Stolorow's "inter-subjective perspective" emerged from self psychology as a full-fledged multi-person point of view. This article considers the significance of contemporary object relations theory and self psychology as relational, multi-person perspectives in terms of their application to group psychotherapy, focusing upon the group-as-a-whole, projective identification, transitional space and object, and self/self-object relations as particularly useful constructs. A clinical vignette is provided.     

A Longitudinal Investigation of Object Relations: Child-Rearing Antecedents,Stability in Adulthood,and Construct Validation

Object relations theories posit that a child's relationship with caregivers has implications for subsequent relationships. Object relations refer to mental representations of relationships. Longitudinal data and Westen's (1993) methodology were employed to investigate questions related to (a) child-rearing antecedents of adult object relations in a nonclinical population, (b) temporal stability of adult object relations, and (c) construct validation. A multivariate effect of child-rearing variables on adult object relations was found, and significant univariate effects were nearly all in the predicted direction. Temporal stability (across 10 years) of adult object relations received tentative support. Object relations correlated positively with interpersonal functioning and physical health, but these correlations tended to be nonsignificant. A positive relationship between object relations and psychological health was not found.     

A Possible Connection between Categorical and Coordinate Spatial Relation Representations

Kosslyn (1987) theorized that the visual system uses two types of spatial relations. Categorical spatial relations represent a range of locations as an equivalence class, whereas coordinate spatial relations represent the precise distance between two objects. Data indicate a left hemisphere (LH) advantage for processing categorical spatial relations and a right hemisphere (RH) advantage for processing coordinate spatial relations. Although generally assumed to be independent processes, this article proposes a possible connection between categorical and coordinate spatial relations. Specifically, categorical spatial relations may be an initial stage in the formation of coordinate spatial relations. Three experiments tested the hypothesis that categorical information would benefit tasks that required coordinate judgments. Experiments 1 and 2 presented categorical information before participants made coordinate judgments and coordinate information before participants made categorical judgments. Categorical information sped the processing of a coordinate task under a range of experimental variables; however, coordinate information did not benefit categorical judgments. Experiment 3 used this priming paradigm to present stimuli in the left or right visual field. Although visual field differences were present in the third experiment, categorical information did not speed the processing of a coordinate task. The lack of priming effects in Experiment 3 may have been due to methodological changes. In general, support is provided that categorical spatial relations may act as an initial step in the formation of more precise distance representations, i.e., coordinate spatial relations.     

The horizontal and vertical relations in upright faces are transmitted by different spatial frequency ranges

Faces convey distinct types of information: features and their spatial relations, which are differentially vulnerable to inversion. While inversion largely disrupts the processing of vertical spatial relations (e.g. eyes’ height), its effect is moderate for horizontal relations (e.g. interocular distance) and local feature properties. The SF ranges optimally transmitting horizontal and vertical face relations were here investigated to further address their functional role in face perception. Participants matched upright and inverted pairs of faces that differed at the level of local featural properties, horizontal relations in vertical relations. Irrespective of SF, the inversion effect was larger for vertical than horizontal and featural cues. Most interestingly, SF differentially influenced the processing of vertical, horizontal and featural cues in upright faces. Vertical relations were optimally processed in intermediate SF, which are known to carry useful information for face individuation. In contrast, horizontal relations were best conveyed by high SF, which are involved in the processing of local face properties. These findings not only confirm that horizontal and vertical relations play distinct functional roles in face perception, but they also further suggest a unique role of vertical relations in face individuation.
