To explain the phenomena in the world of our experience, to answer the question “why?” rather than only the question “what?”, is one of the foremost objectives of all rational inquiry; and especially, scientific research in its various branches strives to go beyond a mere description of its subject matter by providing an explanation of the phenomena it investigates. While there is rather general agreement about this chief objective of science, there exists considerable difference of opinion as to the function (...) and the essential characteristics of scientific explanation. In the present essay, an attempt will be made to shed some light on these issues by means of an elementary survey of the basic pattern of scientific explanation and a subsequent more rigorous analysis of the concept of law and of the logical structure of explanatory arguments.

Despite the changes in human behaviour and interactions occasioned by the COVID-19 pandemic, many institutions are yet to adapt to the new normal fully. While some educational institutions switched entirely to e-learning to promote teaching and learning, others could not offer education due to physical and social restrictions. Previous studies in Africa have identified reasons for the poor ICT adoption for educational purposes. However, the degree to which these factors affect ICT utilisation is barely analysed. Using a quantitative approach, this (...) study assessed ICT deployment for teaching in the COVID-19 era by focusing on their availability and challenges. A sample of 344 respondents from a population of 2,867 academic staff at two Nigerian public universities participated in the study. After receiving face validity from experts, a structured questionnaire was used for data collection. Cronbach alpha reliability indices of the questionnaire ranged from 0.72 to 0.94. Descriptive statistics (simple percentages, mean, and standard deviation) and inferential statistics (one-way ANOVA) were used for data analysis. Findings generally revealed a moderate extent in the availability of ICT resources in public universities. The cost of data, computer literacy, and electricity supply are challenges that significantly affected ICT deployment in the COVID-19 era. Based on this finding, it was concluded that personal and institutional challenges affect how ICT resources are deployed in public universities. It was recommended, among other things, that the management of each tertiary institution should apportion proceeds from internally generated revenue to procure ICT resources specific to the need of the school. The study provides the ground for further research into students’ use of ICT for educational purposes. (shrink)

I report on the fate of three methodological and metatheoretical ideas introduced by Brunswik roughly half a century ago. All were greeted with more than the usual hostility because they challenged the conventional beliefs of the time. All have survived in unexpected ways. I also address certain sins of commission and omission made during the neo-Brunswikian phase of the development of Social Judgement Theory. My hopes and fears for the future are mentioned.

Robert Cummins has recently used the program of Clark Hull to illustrate the effects of logical positivist epistemology upon psychological theory. On Cummins's account, Hull's theory is best understood as a functional analysis, rather than a nomological subsumption. Hull's commitment to the logical positivist view of explanation is said to have blinded him to this aspect of this theory, and thus restricted its scope. We will argue that this interpretation of Hull's epistemology, though common, is mistaken. Hull's epistemological views were (...) developed independently of, and in considerable contrast to, the principles of logical positivism. (shrink)

The present article attempts to investigate the 'philosophical foundations' of psychology and thereby of the social sciences in general with regard to a central problem, viz. the question of the 'inner'. It does this with special critical reference to an authoritative psychological theory, viz. the so-called 'mediation theory', and tries to show the necessity of interdisciplinary clarification. In the first part mediation theory was introduced as a variant of psychological behaviorism which attempts to substitute for the untenable total neglect of (...) 'inner' events a way of talking about them which is secured methodologically and retains a behavioral foundation. Of the three crucial questions raised by the project the second, viz. question, which concerns the theoretical status of the assumed inner mediators could be answered to the effect that they must be "hypothetical constructs" having the nature of real, phenomenally verifiable events, if, indeed, they are to figure as links in S-R-chains. Conceiving of them as "intervening variables", such a conception would exclude this function. The discussion of 'internalization' of behavior sequences as assumed by mediation theory has led to the conclusion that the relevant phenomena cannot, in this case, justify the necessity of a non-dispositional explanation which goes beyond 'external' performances ). Likewise the subject matter of question remained undecided; that is, the possibilities of phenomenally verifying the assumed 'inner' mediation processes which are only asserted to exist by the theory but are unspecified in content. Therefore, the observable performances in the case of sequential behaviour do not support the mediation theoretic solution of the problem of the 'inner'. (shrink)
