We argue that intelligible appeals to interlevel causes (top-down and bottom-up) can be understood, without remainder, as appeals to mechanistically mediated effects. Mechanistically mediated effects are hybrids of causal and constitutive relations, where the causal relations are exclusively intralevel. The idea of causation would have to stretch to the breaking point to accommodate interlevel ...

Many traditional motivation studies have argued that trait motivation strongly controls state motivation. This study, however, focuses more on state motivation and attempts to suggest a bottom-up approach whereby stimulating state motivation through the use of tasks has a potential to positively influence trait motivation. As few studies have argued the task administration and condition in rela...

abstract purpose - the aim of this paper is to describe the population ecology theory through fractal thinking, an emergent human operating system that is creative, adaptive, healthy, and evolutionary; furthermore, a parallel is drawn between the population ecology model and the fractal structure. top-down hierarchies are typically characterized by command and control systems of the authority t...

this study sought to explore the possible relationship between reading anxiety and reading proficiency and also between reading anxiety and language learners’ use of reading strategies. the majority of studies on language anxiety have been quantitative to date. this study was conducted in two phases. the first phase was quantitative, and the second consisted of a series of case studies using in...

objectives: reading is a language skill based on visual modality which recently is addressed as a facilitator of expressive language in children with down syndrome. the aim was designing a whole word reading protocol and examining its effects on the language skills of children with down syndrome. methods: a whole word reading protocol was developed and was examined through a single-subject stud...

Both bottom-up and top-down causation occur in the hierarchy of structure and causation. A key feature is multiple realizability of higher level functions, and consequent existence of equivalence classes of lower level variables that correspond to the same higher level state. Five essentially different classes of top-down influence can be identified, and their existence demonstrated by many rea...
